| 10118 | 14 ** The `lookup' function was extended to be more useful for |
| 15 general-purpose binary searching. Using this improvement, the | |
| 16 ismember function was rewritten for significantly better | |
| 17 performance. | |
| 9352 | 18 |
| 19 ** Real, integer and logical matrices, when used in indexing, will now | |
| 20 cache the internal index_vector value (zero-based indices) when | |
| 21 successfully used as indices, eliminating the conversion penalty for | |
| 10118 | 22 subsequent indexing by the same matrix. In particular, this means it |
| 23 is no longer needed to avoid repeated indexing by logical arrays | |
| 24 using find for performance reasons. | |
| 9888 | 25 |
| 10118 | 26 ** Logical matrices are now treated more efficiently when used as |
| 27 indices. Octave will keep the index as a logical mask unless the | |
| 28 ratio of true elements is small enough, using a specialized | |
| 29 code. Previously, all logical matrices were always first converted | |
| 30 to index vectors. This results in savings in both memory and | |
| 31 computing time. | |
| 9480 | 32 |
| 10118 | 33 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
| 34 functions for better performance. These functions are now faster, | |
| 35 can deliver more economized results for ranges, and can reuse the | |
| 36 index cache mechanism described in previous paragraph. | |
| 37 | |
| 38 ** The built-in function equivalents to associative operators (`plus', | |
| 39 `times', `mtimes', `and', and `or') have been extended to accept | |
| 40 multiple arguments. This is especially useful for summing | |
| 41 (multiplying, etc.) lists of objects (of possibly distinct types): | |
| 9408 | 42 |
| 9449 | 43 matrix_sum = plus (matrix_list{:}); |
| 44 | |
| 10118 | 45 ** An FTP object type based on libcurl has been implemented. These |
| 46 objects allow ftp connections, downloads and uploads to be | |
| 47 managed. For example, | |
| 9880 | 48 |
| 10118 | 49 fp = ftp ("ftp.octave.org); |
| 50 cd (fp, "gnu/octave"); | |
| 51 mget (fp, "octave-3.2.3.tar.bz2"); | |
| 52 close (fp); | |
| 9880 | 53 |
| 10118 | 54 ** The default behavior of `assert (observed, expected)' has been |
| 55 relaxed to employ less strict checking that does not require the | |
| 56 internals of the values to match. This avoids previously valid | |
| 57 tests from breaking due to new internal classes introduced in future | |
| 58 Octave versions. | |
| 9449 | 59 |
| 60 For instance, all of these assertions were true in Octave 3.0.x | |
| 61 but false in 3.2.x due to new optimizations and improvements: | |
| 62 | |
| 63 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
| 64 assert (zeros (0, 0), []) | |
| 65 assert (2*ones (1, 5), (2) (ones (1,5))) | |
| 9462 | 66 |
| 10118 | 67 ** The behavior of library functions `ismatrix', `issquare', and |
| 68 `issymmetric' has been changed for better consistency. | |
| 9873 | 69 |
| 10292 | 70 * The `ismatrix' function now returns true for all numeric, |
| 71 logical and character 2d or Nd matrices. Previously, `ismatrix' | |
| 72 returned false if the first or second dimension was zero. | |
| 73 Hence, `ismatrix ([])' was false, | |
| 74 while `ismatrix (zeros (1,2,0))' was true. | |
| 9873 | 75 |
| 10118 | 76 * The `issquare' function now returns a logical scalar, and is |
| 77 equivalent to the expression | |
| 78 | |
| 79 ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x) | |
| 80 | |
| 81 The dimension is no longer returned. As a result, `issquare ([])' | |
| 82 now yields true. | |
| 9873 | 83 |
| 10118 | 84 * The `issymmetric' function now checks for symmetry instead of |
| 85 hermitianness. For the latter, ishermitian was created. Also, | |
| 86 logical scalar is returned rather than the dimension, so | |
| 87 `issymmetric ([])' is now true. | |
| 9873 | 88 |
| 10118 | 89 ** Function handles are now aware of overloaded functions. If a |
| 90 function is overloaded, the handle determines at the time of its | |
| 91 reference which function to call. A non-overloaded version does not | |
| 92 need to exist. | |
| 9873 | 93 |
| 10118 | 94 ** Overloading functions for built-in classes (double, int8, cell, |
| 95 etc.) is now compatible with Matlab. | |
| 9408 | 96 |
| 10323 | 97 ** Function handles can now be compared with the == and != operators, |
| 98 as well as the `isequal' function. | |
| 99 | |
| 10118 | 100 ** Performance of concatenation (using []) and the functions `cat', |
| 101 `horzcat', and `vertcat' has been improved for multidimensional | |
| 102 arrays. | |
| 10117 | 103 |
| 9547 | 104 ** The operation-assignment operators +=, -=, *= and /= now behave more |
| 10118 | 105 efficiently in certain cases. For instance, if M is a matrix and S a |
| 106 scalar, then the statement | |
| 9547 | 107 |
| 10118 | 108 M += S; |
| 9547 | 109 |
| 10118 | 110 will operate on M's data in-place if it is not shared by another |
| 111 variable, usually increasing both time and memory efficiency. | |
| 9547 | 112 |
| 9558 | 113 Only selected common combinations are affected, namely: |
| 9547 | 114 |
| 115 matrix += matrix | |
| 116 matrix -= matrix | |
| 9558 | 117 matrix .*= matrix |
| 118 matrix ./= matrix | |
| 119 | |
| 9547 | 120 matrix += scalar |
| 121 matrix -= scalar | |
| 122 matrix *= scalar | |
| 123 matrix /= scalar | |
| 9558 | 124 |
| 9552 | 125 logical matrix |= logical matrix |
| 126 logical matrix &= logical matrix | |
| 9547 | 127 |
| 10118 | 128 where matrix and scalar belong to the same class. The left-hand |
| 129 side must be a simple variable reference. | |
| 9888 | 130 |
| 10118 | 131 Moreover, when unary operators occur in expressions, Octave will |
| 132 also try to do the operation in-place if it's argument is a | |
| 133 temporary expresssion. | |
| 9589 | 134 |
| 10118 | 135 ** The effect of comparison operators (<, >, <=, and >=) applied to |
| 136 complex numbers has changed to be consistent with the strict | |
| 137 ordering defined by the `max', `min', and `sort' functions. More | |
| 138 specifically, complex numbers are compared by lexicographical | |
| 139 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
| 140 parts were compared; this can be trivially achieved by wrapping the | |
| 141 operands in real(). | |
| 9547 | 142 |
| 10118 | 143 ** The automatic simplification of complex computation results has |
| 144 changed. Octave will now simplify any complex number with a zero | |
| 145 imaginary part or any complex matrix with all elements having zero | |
| 146 imaginary part to a real value. Previously, this was done only for | |
| 147 positive zeros. Note that the behavior of the complex function is | |
| 148 unchanged and it still produces a complex value even if the | |
| 149 imaginary part is zero. | |
| 9826 | 150 |
| 10118 | 151 ** As a side effect of code refactoring in liboctave, the binary |
| 152 logical operations are now more easily amenable to compiler | |
| 153 optimizations and are thus significantly faster. | |
| 9595 | 154 |
| 10118 | 155 ** Octave now allows user-defined `subsasgn' methods to optimize out |
| 156 redundant copies. For more information, see the manual. | |
| 9595 | 157 |
| 10453 | 158 ** More efficient matrix division handling. Octave is now able to |
| 10118 | 159 handle the expressions |
| 9664 | 160 |
| 10118 | 161 M' \ V |
| 162 M.' \ V | |
| 163 V / M | |
| 9664 | 164 |
| 10118 | 165 (M is a matrix and V is a vector) more efficiently in certain cases. |
| 166 In particular, if M is triangular, all three expressions will be | |
| 167 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
| 10453 | 168 flags. Previously, all three expressions required a physical |
| 10118 | 169 transpose of M. |
| 9664 | 170 |
| 10118 | 171 ** More efficient handling of certain mixed real-complex matrix |
| 172 operations. For instance, if RM is a real matrix and CM a complex | |
| 173 matrix, | |
| 9664 | 174 |
| 10118 | 175 RM * CM |
| 9664 | 176 |
| 177 can now be evaluated either as | |
| 178 | |
| 179 complex (RM * real (CM), RM * imag (CM)) | |
| 180 | |
| 181 or as | |
| 182 | |
| 183 complex (RM) * CM, | |
| 184 | |
| 10453 | 185 depending on the dimensions. The first form requires more |
| 186 temporaries and copying, but halves the FLOP count, which normally | |
| 187 brings better performance if RM has enough rows. Previously, the | |
| 188 second form was always used. | |
| 9664 | 189 |
| 11111 | 190 Matrix division is similarly affected. |
| 9664 | 191 |
| 10118 | 192 ** More efficient handling of triangular matrix factors returned from |
| 193 factorizations. The functions for computing QR, LU and Cholesky | |
| 194 factorizations will now automatically return the triangular matrix | |
| 195 factors with proper internal matrix_type set, so that it won't need | |
| 196 to be computed when the matrix is used for division. | |
| 9717 | 197 |
| 10118 | 198 ** The built-in `sum' function now handles the non-native summation |
| 199 (i.e., double precision sum of single or integer inputs) more | |
| 200 efficiently, avoiding a temporary conversion of the whole input | |
| 201 array to doubles. Further, `sum' can now accept an extra option | |
| 202 argument, using a compensated summation algorithm rather than a | |
| 203 straightforward sum, which significantly improves precision if lots | |
| 204 of cancellation occurs in the summation. | |
| 9717 | 205 |
| 10118 | 206 ** The built-in `bsxfun' function now uses optimized code for certain |
| 207 cases where built-in operator handles are passed in. Namely, the | |
| 208 optimizations concern the operators `plus', `minus', `times', | |
| 209 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
| 210 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
| 211 functions `min' and `max'. Optimizations only apply when both | |
| 212 operands are of the same built-in class. Mixed real/complex and | |
| 213 single/double operations will first convert both operands to a | |
| 214 common type. | |
| 9745 | 215 |
| 10118 | 216 ** The `strfind' and `strrep' functions now have compiled |
| 217 implementations, facilitating significantly more efficient searching | |
| 218 and replacing in strings, especially with longer patterns. The code | |
| 219 of `strcat' has been vectorized and is now much more efficient when | |
| 220 many strings are concatenated. The `strcmpi' and `strncmpi' | |
| 221 functions are now built-in functions, providing better performance. | |
| 10208 | 222 |
| 10453 | 223 ** Matlab-style ignoring input and output function arguments using |
| 11111 | 224 tilde (~) is now supported. Ignored output arguments may be |
| 225 detected from a function using the built-in function `isargout'. | |
| 226 For more details, consult the manual. | |
| 10886 | 227 |
| 10453 | 228 ** The list datatype, deprecated since the introduction of cells, has |
| 229 been removed. | |
| 10276 | 230 |
| 10453 | 231 ** The accumarray function has been optimized and is now significantly |
| 232 faster in certain important cases. | |
| 10054 | 233 |
| 10292 | 234 ** The behavior of isreal and isnumeric functions was changed to be more |
| 235 Matlab-compatible. | |
| 236 | |
| 10406 | 237 ** The integer math & conversion warnings (Octave:int-convert-nan, |
| 238 Octave:int-convert-non-int-val, Octave:int-convert-overflow, | |
| 11111 | 239 Octave:int-math-overflow) have been removed. |
| 10406 | 240 |
| 10453 | 241 ** rem and mod are now built-in functions. They also handle integer |
| 242 types efficiently using integer arithmetic. | |
| 10437 | 243 |
| 10536 | 244 ** Sparse indexing and indexed assignment has been mostly rewritten. |
| 245 Since Octave uses compressed column storage for sparse matrices, | |
| 246 major attention is devoted to operations manipulating whole columns. | |
| 247 Such operations are now significantly faster, as well as some other | |
| 248 important cases. | |
| 249 | |
| 250 Further, it is now possible to pre-allocate a sparse matrix and | |
| 251 subsequently fill it by assignments, provided they meet certain | |
| 252 conditions. For more information, consult the `spalloc' function, | |
| 253 which is no longer a mere dummy. Consequently, nzmax and nnz are no | |
| 11111 | 254 longer always equal in Octave. Octave may also produce a matrix |
| 255 with nnz < nzmax as a result of other operations, so you should | |
| 256 consistently use nnz unless you really want to use nzmax (i.e. the | |
| 257 space allocated for nonzero elements). | |
| 10536 | 258 |
| 259 Sparse concatenation is also affected, and concatenating sparse | |
| 260 matrices, especially larger collections, is now significantly more | |
| 11111 | 261 efficient. This applies to both the [] operator and the |
| 10536 | 262 cat/vertcat/horzcat functions. |
| 263 | |
| 11111 | 264 ** It is now possible to optionally employ the xGESDD LAPACK drivers |
| 265 for computing the singular value decomposition using svd(), instead | |
| 266 of the default xGESVD, using the configuration pseudo-variable | |
| 267 svd_driver. The xGESDD driver can be up to 6x times faster when | |
| 268 singular vectors are requested, but is reported to be somewhat less | |
| 10639 | 269 robust on highly ill-conditioned matrices. |
| 270 | |
| 271 ** Configuration pseudo-variables, such as page_screen_output or | |
| 272 confirm_recursive_rmdir (or the above mentioned svd_driver), now | |
| 273 accept a "local" option as second argument, requesting the change | |
| 274 to be undone when current function returns: | |
| 275 | |
| 276 function [status, msg] = rm_rf (dir) | |
| 277 confirm_recursive_rmdir (false, "local"); | |
| 278 [status, msg] = rmdir (dir, "s"); | |
| 279 ... | |
| 280 endfunction | |
| 281 | |
| 282 Upon return, confirm_recursive_rmdir will be restored to the value | |
| 283 it had on entry to the function, even if there were subsequent | |
| 284 changes to the variable in function rm_rf or any of the functions | |
| 285 it calls. | |
| 286 | |
| 11111 | 287 ** pkg now accepts a -forge option for downloading and installing |
| 288 packages from Octave Forge automatically. For example, | |
| 10774 | 289 |
| 290 pkg install -forge general | |
| 291 | |
| 11111 | 292 will automatically download the latest release of the general |
| 293 package and attempt to install it. No automatic resolving of | |
| 294 dependencies is provided. Further, | |
| 10639 | 295 |
| 10774 | 296 pkg list -forge |
| 297 | |
| 298 can be used to list all available packages. | |
| 299 | |
| 11111 | 300 ** The internal data representation of structs has been completely |
| 301 rewritten to make certain optimizations feasible. The field data | |
| 302 can now be shared between structs with equal keys but different | |
| 303 dimensions or values, making operations that preserve the fields | |
| 304 faster. Economized storage is now used for scalar structs (just | |
| 305 like most other scalars), making their usage more | |
| 306 memory-efficient. Certain array-like operations on structs | |
| 307 (concatenation, uniform cellfun, num2cell) have gained a | |
| 308 significant speed-up. Additionally, the octave_scalar_map class | |
| 309 now provides a simpler interface to work with scalar structs within | |
| 310 a C++ DLD function. | |

| 11111 | 344 ** The dlmread function has been extended to allow specifying a custom |
| 345 value for empty fields. | |
| 10829 | 346 |
| 11111 | 347 ** The dlmread and dlmwrite functions have been modified to accept |
| 348 file IDs (as returned by fopen) in addition to file names. | |
| 349 | |
| 350 ** Octave can now optimize away the interpreter overhead of an | |
| 351 anonymous function handle, if the function simply calls another | |
| 352 function or handle with some of its parameters bound to certain | |
| 353 values. Example: | |
| 10966 | 354 |
| 355 f = @(x) sum (x, 1); | |
| 356 | |
| 11111 | 357 When f is called, the call is forwarded to @sum with the constant 1 |
| 358 appended, and the anonymous function call does not occur on the | |
| 359 call stack. | |

| 480 These functions are now available as separate packages from | |
| 481 | |
| 482 http://octave.sourceforge.net/packages.html | |
| 483 | |
| 484 and can be reinstalled using the Octave package manager (see | |
| 485 the pkg function). | |
| 486 | |
| 487 ** Specific sparse matrix functions removed. | |
| 488 | |
| 489 The following functions, which handled only sparse matrices have | |
| 490 been removed. Instead of calling these functions directly, you | |
| 491 should use the corresponding function without the "sp" prefix. | |
| 8737 | 492 |
| 8885 | 493 spatan2 spcumsum spkron spprod |
| 494 spchol spdet splchol spqr | |
| 495 spchol2inv spdiag splu spsum | |
| 496 spcholinv spfind spmax spsumsqk | |
| 497 spcumprod spinv spmin | |
| 498 | |
| 499 ** Improvements to the debugger. | |
| 500 | |
| 501 The interactive debugging features have been improved. Stopping | |
| 502 on statements with dbstop should work correctly now. Stepping | |
| 503 into and over functions, and stepping one statement at a time | |
| 504 (with dbstep) now works. Moving up and down the call stack with | |
| 505 dbup and dbdown now works. The dbstack function is now available | |
| 506 to print the current function call stack. The new dbquit function | |
| 507 is available to exit the debugging mode. | |
| 508 | |
| 509 ** Improved traceback error messages. | |
| 510 | |
| 511 Traceback error messages are much more concise and easier to | |
| 512 understand. They now display information about the function call | |
| 513 stack instead of the stack of all statements that were active at | |
| 514 the point of the error. | |

| 8737 | 518 Octave now includes OOP features and the user can create their own |
| 519 class objects and overloaded functions and operators. For | |
| 520 example, all methods of a class called "myclass" will be found in | |
| 521 a directory "@myclass" on the users path. The class specific | |
| 522 versions of functions and operators take precedence over the | |
| 523 generic versions of these functions. | |
| 524 | |
| 525 New functions related to OOP include | |
| 7189 | 526 |
| 8737 | 527 class inferiorto isobject loadobj methods superiorto |
| 528 | |
| 529 See the Octave manual for more details. | |
| 7038 | 530 |
| 8747 | 531 ** Parsing of Command-style Functions. |
| 532 | |
| 533 Octave now parses command-style functions without needing to first | |
| 534 declare them with "mark_as_command". The rules for recognizing a | |
| 535 command-style function calls are | |
| 536 | |
| 537 * A command must appear as the first word in a statement, | |
| 538 followed by a space. | |
| 539 | |
| 540 * The first character after the space must not be '=' or '(' | |
| 541 | |
| 542 * The next token after the space must not look like a binary | |
| 543 operator. | |
| 544 | |
| 545 These rules should be mostly compatible with the way Matlab parses | |
| 546 command-style function calls and allow users to define commands in | |
| 547 .m files without having to mark them as commands. | |
| 548 | |
| 549 Note that previous versions of Octave allowed expressions like | |
| 550 | |
| 551 x = load -text foo.dat | |
| 552 | |
| 553 but an expression like this will now generate a parse error. In | |
| 554 order to assign the value returned by a function to a variable, | |
| 555 you must use the normal function call syntax: | |
| 556 | |
| 557 x = load ("-text", "foo.dat"); | |
| 558 | |
| 8737 | 559 ** Block comments. |
| 560 | |
| 8747 | 561 Commented code can be between matching "#{" and "#}" or "%{" and |
| 562 "%}" markers, even if the commented code spans several line. This | |
| 563 allows blocks code to be commented, without needing to comment | |
| 564 each line. For example, | |
| 5814 | 565 |
| 8747 | 566 function [s, t] = func (x, y) |
| 567 s = 2 * x; | |
| 568 #{ | |
| 569 s *= y; | |
| 570 t = y + x; | |
| 571 #} | |

615 conversions between cells, structs and cs-lists. This usually reduces |
| 8755 | 616 both time and memory consumption. |
| 9128 | 617 Also, Octave will now attempt to detect and optimize usage of a vector |
| 618 as a stack, when elements are being repeatedly inserted at/removed from | |
| 619 the end of the vector. | |
| 8755 | 620 |
| 8738 | 621 ** Improved performance for reduction operations. |
| 622 | |
| 8755 | 623 The performance of the sum, prod, sumsq, cumsum, cumprod, any, all, |
| 624 max and min functions has been significantly improved. | |
| 8738 | 625 |
| 9006 | 626 ** Sorting and searching. |
| 627 | |
| 628 The performance of sort has been improved, especially when sorting | |
| 10453 | 629 indices are requested. An efficient built-in issorted |
| 630 implementation was added. The sortrows function now uses a more | |
| 631 efficient algorithm, especially in the homegeneous case. The lookup | |
| 632 function is now a built-in function performing a binary search, | |
| 633 optimized for long runs of close elements. Lookup also works with | |
| 634 cell arrays of strings. | |
| 9006 | 635 |
| 636 ** Range arithmetics | |
| 637 | |
| 10453 | 638 For some operations on ranges, Octave will attempt to keep the |
| 639 result as a range. These include negation, adding a scalar, | |
| 640 subtracting a scalar, and multiplying by a scalar. Ranges with zero | |
| 641 increment are allowed and can be constructed using the built-in | |
| 642 function `ones'. | |
| 9006 | 643 |
| 644 ** Various performance improvements. | |
| 645 | |
| 10453 | 646 Performance of a number of other built-in operations and functions |
| 647 was improved, including: | |
| 9006 | 648 |
| 649 * logical operations | |
| 650 * comparison operators | |
| 651 * element-wise power | |
| 652 * accumarray | |
| 653 * cellfun | |
| 654 * isnan | |
| 655 * isinf | |
| 656 * isfinite | |
| 657 * nchoosek | |
| 658 * repmat | |
| 659 * strcmp | |
| 660 | |
| 8737 | 661 ** 64-bit integer arithmetic. |
| 662 | |
| 663 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
| 664 supported, with saturation semantics like the other integer types. | |
| 665 Performance of most integer arithmetic operations has been | |
| 666 improved by using integer arithmetic directly. Previously, Octave | |
| 667 performed integer math with saturation semantics by converting the | |
| 668 operands to double precision, performing the operation, and then | |
| 669 converting the result back to an integer value, truncating if | |
| 670 necessary. | |
| 671 | |
| 8885 | 672 ** Diagonal and permutation matrices. |
| 673 | |
| 674 The interpreter can now treat diagonal and permutation matrices as | |
| 675 special objects that store only the non-zero elements, rather than | |
| 676 general full matrices. Therefore, it is now possible to construct | |
| 677 and use these matrices in linear algebra without suffering a | |
| 678 performance penalty due to storing large numbers of zero elements. | |
| 679 | |
| 680 ** Improvements to fsolve. | |
| 681 | |
| 682 The fsolve function now accepts an option structure argument (see | |
| 683 also the optimset function). The INFO values returned from fsolve | |
| 684 have changed to be compatible with Matlab's fsolve function. | |
| 685 Additionally, fsolve is now able to solve overdetermined systems, | |
| 686 complex-differentiable complex systems, systems with a sparse | |
| 687 jacobian and can work in single precision if given single precision | |

| 693 matrix in a single call, as well as general matrix p-norms. | |
| 694 | |
| 695 ** New functions for computing some eigenvalues or singular values. | |
