| 10118 | 69 ** The `lookup' function was extended to be more useful for |
| 70 general-purpose binary searching. Using this improvement, the | |
| 71 ismember function was rewritten for significantly better | |
| 72 performance. | |
| 9352 | 73 |
| 74 ** Real, integer and logical matrices, when used in indexing, will now | |
| 75 cache the internal index_vector value (zero-based indices) when | |
| 76 successfully used as indices, eliminating the conversion penalty for | |
| 10118 | 77 subsequent indexing by the same matrix. In particular, this means it |
| 78 is no longer needed to avoid repeated indexing by logical arrays | |
| 79 using find for performance reasons. | |
| 9888 | 80 |
| 10118 | 81 ** Logical matrices are now treated more efficiently when used as |
| 82 indices. Octave will keep the index as a logical mask unless the | |
| 83 ratio of true elements is small enough, using a specialized | |
| 84 code. Previously, all logical matrices were always first converted | |
| 85 to index vectors. This results in savings in both memory and | |
| 86 computing time. | |
| 9480 | 87 |
| 10118 | 88 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
| 89 functions for better performance. These functions are now faster, | |
| 90 can deliver more economized results for ranges, and can reuse the | |
| 91 index cache mechanism described in previous paragraph. | |
| 92 | |
| 93 ** The built-in function equivalents to associative operators (`plus', | |
| 94 `times', `mtimes', `and', and `or') have been extended to accept | |
| 95 multiple arguments. This is especially useful for summing | |
| 96 (multiplying, etc.) lists of objects (of possibly distinct types): | |
| 9408 | 97 |
| 9449 | 98 matrix_sum = plus (matrix_list{:}); |
| 99 | |
| 10118 | 100 ** An FTP object type based on libcurl has been implemented. These |
| 101 objects allow ftp connections, downloads and uploads to be | |
| 102 managed. For example, | |
| 9880 | 103 |
| 10118 | 104 fp = ftp ("ftp.octave.org); |
| 105 cd (fp, "gnu/octave"); | |
| 106 mget (fp, "octave-3.2.3.tar.bz2"); | |
| 107 close (fp); | |
| 9880 | 108 |
| 10118 | 109 ** The default behavior of `assert (observed, expected)' has been |
| 110 relaxed to employ less strict checking that does not require the | |
| 111 internals of the values to match. This avoids previously valid | |
| 112 tests from breaking due to new internal classes introduced in future | |
| 113 Octave versions. | |
| 9449 | 114 |
| 115 For instance, all of these assertions were true in Octave 3.0.x | |
| 116 but false in 3.2.x due to new optimizations and improvements: | |
| 117 | |
| 118 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
| 119 assert (zeros (0, 0), []) | |
| 120 assert (2*ones (1, 5), (2) (ones (1,5))) | |
| 9462 | 121 |
| 10118 | 122 ** The behavior of library functions `ismatrix', `issquare', and |
| 123 `issymmetric' has been changed for better consistency. | |
| 9873 | 124 |
| 10292 | 125 * The `ismatrix' function now returns true for all numeric, |

126 logical and character 2-D or N-D matrices. Previously, `ismatrix' |
| 10292 | 127 returned false if the first or second dimension was zero. |
| 128 Hence, `ismatrix ([])' was false, | |
| 129 while `ismatrix (zeros (1,2,0))' was true. | |
| 9873 | 130 |
| 10118 | 131 * The `issquare' function now returns a logical scalar, and is |
| 132 equivalent to the expression | |
| 133 | |
| 134 ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x) | |
| 135 | |
| 136 The dimension is no longer returned. As a result, `issquare ([])' | |
| 137 now yields true. | |
| 9873 | 138 |
| 10118 | 139 * The `issymmetric' function now checks for symmetry instead of |

140 Hermitianness. For the latter, ishermitian was created. Also, |
| 10118 | 141 logical scalar is returned rather than the dimension, so |
| 142 `issymmetric ([])' is now true. | |
| 9873 | 143 |
| 10118 | 144 ** Function handles are now aware of overloaded functions. If a |
| 145 function is overloaded, the handle determines at the time of its | |
| 146 reference which function to call. A non-overloaded version does not | |
| 147 need to exist. | |
| 9873 | 148 |
| 10118 | 149 ** Overloading functions for built-in classes (double, int8, cell, |
| 150 etc.) is now compatible with Matlab. | |
| 9408 | 151 |
| 10323 | 152 ** Function handles can now be compared with the == and != operators, |
| 153 as well as the `isequal' function. | |
| 154 | |
| 10118 | 155 ** Performance of concatenation (using []) and the functions `cat', |
| 156 `horzcat', and `vertcat' has been improved for multidimensional | |
| 157 arrays. | |
| 10117 | 158 |
| 9547 | 159 ** The operation-assignment operators +=, -=, *= and /= now behave more |
| 10118 | 160 efficiently in certain cases. For instance, if M is a matrix and S a |
| 161 scalar, then the statement | |
| 9547 | 162 |
| 10118 | 163 M += S; |
| 9547 | 164 |
| 10118 | 165 will operate on M's data in-place if it is not shared by another |
| 166 variable, usually increasing both time and memory efficiency. | |
| 9547 | 167 |
| 9558 | 168 Only selected common combinations are affected, namely: |
| 9547 | 169 |
| 170 matrix += matrix | |
| 171 matrix -= matrix | |
| 9558 | 172 matrix .*= matrix |
| 173 matrix ./= matrix | |
| 174 | |
| 9547 | 175 matrix += scalar |
| 176 matrix -= scalar | |
| 177 matrix *= scalar | |
| 178 matrix /= scalar | |
| 9558 | 179 |
| 9552 | 180 logical matrix |= logical matrix |
| 181 logical matrix &= logical matrix | |
| 9547 | 182 |
| 10118 | 183 where matrix and scalar belong to the same class. The left-hand |
| 184 side must be a simple variable reference. | |
| 9888 | 185 |
| 10118 | 186 Moreover, when unary operators occur in expressions, Octave will |
| 187 also try to do the operation in-place if it's argument is a | |

188 temporary expression. |
| 9589 | 189 |
| 10118 | 190 ** The effect of comparison operators (<, >, <=, and >=) applied to |
| 191 complex numbers has changed to be consistent with the strict | |
| 192 ordering defined by the `max', `min', and `sort' functions. More | |
| 193 specifically, complex numbers are compared by lexicographical | |
| 194 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
| 195 parts were compared; this can be trivially achieved by wrapping the | |
| 196 operands in real(). | |
| 9547 | 197 |
| 10118 | 198 ** The automatic simplification of complex computation results has |
| 199 changed. Octave will now simplify any complex number with a zero | |
| 200 imaginary part or any complex matrix with all elements having zero | |
| 201 imaginary part to a real value. Previously, this was done only for | |
| 202 positive zeros. Note that the behavior of the complex function is | |
| 203 unchanged and it still produces a complex value even if the | |
| 204 imaginary part is zero. | |
| 9826 | 205 |
| 10118 | 206 ** As a side effect of code refactoring in liboctave, the binary |
| 207 logical operations are now more easily amenable to compiler | |
| 208 optimizations and are thus significantly faster. | |
| 9595 | 209 |
| 10118 | 210 ** Octave now allows user-defined `subsasgn' methods to optimize out |
| 211 redundant copies. For more information, see the manual. | |
| 9595 | 212 |
| 10453 | 213 ** More efficient matrix division handling. Octave is now able to |
| 10118 | 214 handle the expressions |

218 V / M |
| 9664 | 219 |
| 10118 | 220 (M is a matrix and V is a vector) more efficiently in certain cases. |
| 221 In particular, if M is triangular, all three expressions will be | |
| 222 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
| 10453 | 223 flags. Previously, all three expressions required a physical |
| 10118 | 224 transpose of M. |
| 9664 | 225 |
| 10118 | 226 ** More efficient handling of certain mixed real-complex matrix |
| 227 operations. For instance, if RM is a real matrix and CM a complex | |
| 228 matrix, | |
| 9664 | 229 |
| 10118 | 230 RM * CM |
| 9664 | 231 |
| 232 can now be evaluated either as | |
| 233 | |
| 234 complex (RM * real (CM), RM * imag (CM)) | |
| 235 | |
| 236 or as | |
| 237 | |
| 238 complex (RM) * CM, | |
| 239 | |
| 10453 | 240 depending on the dimensions. The first form requires more |
| 241 temporaries and copying, but halves the FLOP count, which normally | |
| 242 brings better performance if RM has enough rows. Previously, the | |
| 243 second form was always used. | |
| 9664 | 244 |
| 11111 | 245 Matrix division is similarly affected. |
| 9664 | 246 |
| 10118 | 247 ** More efficient handling of triangular matrix factors returned from |
| 248 factorizations. The functions for computing QR, LU and Cholesky | |
| 249 factorizations will now automatically return the triangular matrix | |
| 250 factors with proper internal matrix_type set, so that it won't need | |
| 251 to be computed when the matrix is used for division. | |
| 9717 | 252 |
| 10118 | 253 ** The built-in `sum' function now handles the non-native summation |
| 254 (i.e., double precision sum of single or integer inputs) more | |
| 255 efficiently, avoiding a temporary conversion of the whole input | |
| 256 array to doubles. Further, `sum' can now accept an extra option | |
| 257 argument, using a compensated summation algorithm rather than a | |
| 258 straightforward sum, which significantly improves precision if lots | |
| 259 of cancellation occurs in the summation. | |
| 9717 | 260 |
| 10118 | 261 ** The built-in `bsxfun' function now uses optimized code for certain |
| 262 cases where built-in operator handles are passed in. Namely, the | |
| 263 optimizations concern the operators `plus', `minus', `times', | |
| 264 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
| 265 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
| 266 functions `min' and `max'. Optimizations only apply when both | |
| 267 operands are of the same built-in class. Mixed real/complex and | |
| 268 single/double operations will first convert both operands to a | |
| 269 common type. | |
| 9745 | 270 |
| 10118 | 271 ** The `strfind' and `strrep' functions now have compiled |
| 272 implementations, facilitating significantly more efficient searching | |
| 273 and replacing in strings, especially with longer patterns. The code | |
| 274 of `strcat' has been vectorized and is now much more efficient when | |
| 275 many strings are concatenated. The `strcmpi' and `strncmpi' | |
| 276 functions are now built-in functions, providing better performance. | |

281 has been removed. |

| 10453 | 283 ** Matlab-style ignoring input and output function arguments using |
| 11111 | 284 tilde (~) is now supported. Ignored output arguments may be |
| 285 detected from a function using the built-in function `isargout'. | |
| 286 For more details, consult the manual. | |
| 10886 | 287 |
| 10453 | 288 ** The list datatype, deprecated since the introduction of cells, has |
| 289 been removed. | |
| 10276 | 290 |
| 10453 | 291 ** The accumarray function has been optimized and is now significantly |
| 292 faster in certain important cases. | |
| 10054 | 293 |
| 10292 | 294 ** The behavior of isreal and isnumeric functions was changed to be more |
| 295 Matlab-compatible. | |
| 296 | |
| 10406 | 297 ** The integer math & conversion warnings (Octave:int-convert-nan, |
| 298 Octave:int-convert-non-int-val, Octave:int-convert-overflow, | |
| 11111 | 299 Octave:int-math-overflow) have been removed. |
| 10406 | 300 |
| 10453 | 301 ** rem and mod are now built-in functions. They also handle integer |
| 302 types efficiently using integer arithmetic. | |
| 10437 | 303 |
| 10536 | 304 ** Sparse indexing and indexed assignment has been mostly rewritten. |
| 305 Since Octave uses compressed column storage for sparse matrices, | |
| 306 major attention is devoted to operations manipulating whole columns. | |
| 307 Such operations are now significantly faster, as well as some other | |
| 308 important cases. | |
| 309 | |
| 310 Further, it is now possible to pre-allocate a sparse matrix and | |
| 311 subsequently fill it by assignments, provided they meet certain | |
| 312 conditions. For more information, consult the `spalloc' function, | |
| 313 which is no longer a mere dummy. Consequently, nzmax and nnz are no | |
| 11111 | 314 longer always equal in Octave. Octave may also produce a matrix |
| 315 with nnz < nzmax as a result of other operations, so you should | |
| 316 consistently use nnz unless you really want to use nzmax (i.e. the | |
| 317 space allocated for nonzero elements). | |
| 10536 | 318 |
| 319 Sparse concatenation is also affected, and concatenating sparse | |
| 320 matrices, especially larger collections, is now significantly more | |
| 11111 | 321 efficient. This applies to both the [] operator and the |
| 10536 | 322 cat/vertcat/horzcat functions. |
| 323 | |
| 11111 | 324 ** It is now possible to optionally employ the xGESDD LAPACK drivers |
| 325 for computing the singular value decomposition using svd(), instead | |
| 326 of the default xGESVD, using the configuration pseudo-variable | |
| 327 svd_driver. The xGESDD driver can be up to 6x times faster when | |
| 328 singular vectors are requested, but is reported to be somewhat less | |
| 10639 | 329 robust on highly ill-conditioned matrices. |
| 330 | |
| 331 ** Configuration pseudo-variables, such as page_screen_output or | |
| 332 confirm_recursive_rmdir (or the above mentioned svd_driver), now | |
| 333 accept a "local" option as second argument, requesting the change | |

| 341 | |
| 342 Upon return, confirm_recursive_rmdir will be restored to the value | |
| 343 it had on entry to the function, even if there were subsequent | |
| 344 changes to the variable in function rm_rf or any of the functions | |
| 345 it calls. | |
| 346 | |
| 11111 | 347 ** pkg now accepts a -forge option for downloading and installing |

547 __gnuplot_show__, __gnuplot_replot__, __gnuplot_splot__, |
| 8737 | 548 __gnuplot_save_data__ and __gnuplot_send_inline_data__ have been |
| 549 removed from Octave. These function were incompatible with the | |
| 550 high level graphics handle code. | |
| 6329 | 551 |
| 8885 | 552 ** The Control, Finance and Quaternion functions have been removed. |
| 553 | |
| 554 These functions are now available as separate packages from | |
| 555 | |
| 556 http://octave.sourceforge.net/packages.html | |
| 557 | |
| 558 and can be reinstalled using the Octave package manager (see | |
| 559 the pkg function). | |
| 560 | |
| 561 ** Specific sparse matrix functions removed. | |
| 562 | |
| 563 The following functions, which handled only sparse matrices have | |
| 564 been removed. Instead of calling these functions directly, you | |
| 565 should use the corresponding function without the "sp" prefix. | |
| 8737 | 566 |

| 568 spchol spdet splchol spqr | |

| 571 spcumprod spinv spmin | |
| 572 | |
| 573 ** Improvements to the debugger. | |
| 574 | |
| 575 The interactive debugging features have been improved. Stopping | |
| 576 on statements with dbstop should work correctly now. Stepping | |
| 577 into and over functions, and stepping one statement at a time | |
| 578 (with dbstep) now works. Moving up and down the call stack with | |
| 579 dbup and dbdown now works. The dbstack function is now available | |
| 580 to print the current function call stack. The new dbquit function | |
| 581 is available to exit the debugging mode. | |
| 582 | |
| 583 ** Improved traceback error messages. | |
| 584 | |
| 585 Traceback error messages are much more concise and easier to | |
| 586 understand. They now display information about the function call | |
| 587 stack instead of the stack of all statements that were active at | |
| 588 the point of the error. | |

591 |
| 8737 | 592 Octave now includes OOP features and the user can create their own |
| 593 class objects and overloaded functions and operators. For | |
| 594 example, all methods of a class called "myclass" will be found in | |
| 595 a directory "@myclass" on the users path. The class specific | |
| 596 versions of functions and operators take precedence over the | |
| 597 generic versions of these functions. | |
| 598 | |
| 599 New functions related to OOP include | |
| 7189 | 600 |
| 8737 | 601 class inferiorto isobject loadobj methods superiorto |
| 602 | |
| 603 See the Octave manual for more details. | |
| 7038 | 604 |
| 8747 | 605 ** Parsing of Command-style Functions. |
| 606 | |
| 607 Octave now parses command-style functions without needing to first | |
| 608 declare them with "mark_as_command". The rules for recognizing a | |
| 609 command-style function calls are | |
| 610 | |
| 611 * A command must appear as the first word in a statement, | |
| 612 followed by a space. | |
| 613 | |
| 614 * The first character after the space must not be '=' or '(' | |
| 615 | |
| 616 * The next token after the space must not look like a binary | |
| 617 operator. | |
| 618 | |
| 619 These rules should be mostly compatible with the way Matlab parses | |
| 620 command-style function calls and allow users to define commands in | |
| 621 .m files without having to mark them as commands. | |
| 622 | |
| 623 Note that previous versions of Octave allowed expressions like | |
| 624 | |
| 625 x = load -text foo.dat | |
| 626 | |
| 627 but an expression like this will now generate a parse error. In | |
| 628 order to assign the value returned by a function to a variable, | |
| 629 you must use the normal function call syntax: | |
| 630 | |
| 631 x = load ("-text", "foo.dat"); | |
| 632 | |
| 8737 | 633 ** Block comments. |
| 634 | |
| 8747 | 635 Commented code can be between matching "#{" and "#}" or "%{" and |
| 636 "%}" markers, even if the commented code spans several line. This | |
| 637 allows blocks code to be commented, without needing to comment | |
| 638 each line. For example, | |
| 5814 | 639 |
| 8747 | 640 function [s, t] = func (x, y) |

701 conversions between cells, structs and cs-lists. This usually reduces |
| 8755 | 702 both time and memory consumption. |
| 9128 | 703 Also, Octave will now attempt to detect and optimize usage of a vector |
| 704 as a stack, when elements are being repeatedly inserted at/removed from | |
| 705 the end of the vector. | |
| 8755 | 706 |
| 8738 | 707 ** Improved performance for reduction operations. |

717 efficient algorithm, especially in the homogeneous case. The lookup |
| 10453 | 718 function is now a built-in function performing a binary search, |
| 719 optimized for long runs of close elements. Lookup also works with | |
| 720 cell arrays of strings. | |
| 9006 | 721 |
| 722 ** Range arithmetics | |
| 723 | |
| 10453 | 724 For some operations on ranges, Octave will attempt to keep the |
| 725 result as a range. These include negation, adding a scalar, | |
| 726 subtracting a scalar, and multiplying by a scalar. Ranges with zero | |
| 727 increment are allowed and can be constructed using the built-in | |
| 728 function `ones'. | |
| 9006 | 729 |
| 730 ** Various performance improvements. | |
| 731 | |
| 10453 | 732 Performance of a number of other built-in operations and functions |
| 733 was improved, including: | |
| 9006 | 734 |
| 735 * logical operations | |
| 736 * comparison operators | |
| 737 * element-wise power | |
| 738 * accumarray | |
| 739 * cellfun | |
| 740 * isnan | |
| 741 * isinf | |
| 742 * isfinite | |
| 743 * nchoosek | |
| 744 * repmat | |
| 745 * strcmp | |
| 746 | |
| 8737 | 747 ** 64-bit integer arithmetic. |
| 748 | |
| 749 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
| 750 supported, with saturation semantics like the other integer types. | |
| 751 Performance of most integer arithmetic operations has been | |
| 752 improved by using integer arithmetic directly. Previously, Octave | |
| 753 performed integer math with saturation semantics by converting the | |
| 754 operands to double precision, performing the operation, and then | |
| 755 converting the result back to an integer value, truncating if | |
| 756 necessary. | |
| 757 | |
| 8885 | 758 ** Diagonal and permutation matrices. |
| 759 | |
| 760 The interpreter can now treat diagonal and permutation matrices as | |
| 761 special objects that store only the non-zero elements, rather than | |
| 762 general full matrices. Therefore, it is now possible to construct | |
| 763 and use these matrices in linear algebra without suffering a | |
| 764 performance penalty due to storing large numbers of zero elements. | |
| 765 | |
| 766 ** Improvements to fsolve. | |
| 767 | |
| 768 The fsolve function now accepts an option structure argument (see | |
| 769 also the optimset function). The INFO values returned from fsolve | |
| 770 have changed to be compatible with Matlab's fsolve function. | |
| 771 Additionally, fsolve is now able to solve overdetermined systems, | |
| 772 complex-differentiable complex systems, systems with a sparse | |
| 773 jacobian and can work in single precision if given single precision | |

| 781 ** New functions for computing some eigenvalues or singular values. | |
| 782 | |
| 783 The eigs and svds functions have been included in Octave. These | |
