10118 | 8 ** The `lookup' function was extended to be more useful for |
9 general-purpose binary searching. Using this improvement, the | |
10 ismember function was rewritten for significantly better | |
11 performance. | |
9352 | 12 |
13 ** Real, integer and logical matrices, when used in indexing, will now | |
14 cache the internal index_vector value (zero-based indices) when | |
15 successfully used as indices, eliminating the conversion penalty for | |
10118 | 16 subsequent indexing by the same matrix. In particular, this means it |
17 is no longer needed to avoid repeated indexing by logical arrays | |
18 using find for performance reasons. | |
9888 | 19 |
10118 | 20 ** Logical matrices are now treated more efficiently when used as |
21 indices. Octave will keep the index as a logical mask unless the | |
22 ratio of true elements is small enough, using a specialized | |
23 code. Previously, all logical matrices were always first converted | |
24 to index vectors. This results in savings in both memory and | |
25 computing time. | |
9480 | 26 |
10118 | 27 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
28 functions for better performance. These functions are now faster, | |
29 can deliver more economized results for ranges, and can reuse the | |
30 index cache mechanism described in previous paragraph. | |
31 | |
32 ** The built-in function equivalents to associative operators (`plus', | |
33 `times', `mtimes', `and', and `or') have been extended to accept | |
34 multiple arguments. This is especially useful for summing | |
35 (multiplying, etc.) lists of objects (of possibly distinct types): | |
9408 | 36 |
9449 | 37 matrix_sum = plus (matrix_list{:}); |
38 | |
10118 | 39 ** An FTP object type based on libcurl has been implemented. These |
40 objects allow ftp connections, downloads and uploads to be | |
41 managed. For example, | |
9880 | 42 |
10118 | 43 fp = ftp ("ftp.octave.org); |
44 cd (fp, "gnu/octave"); | |
45 mget (fp, "octave-3.2.3.tar.bz2"); | |
46 close (fp); | |
9880 | 47 |
10118 | 48 ** The default behavior of `assert (observed, expected)' has been |
49 relaxed to employ less strict checking that does not require the | |
50 internals of the values to match. This avoids previously valid | |
51 tests from breaking due to new internal classes introduced in future | |
52 Octave versions. | |
9449 | 53 |
54 For instance, all of these assertions were true in Octave 3.0.x | |
55 but false in 3.2.x due to new optimizations and improvements: | |
56 | |
57 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
58 assert (zeros (0, 0), []) | |
59 assert (2*ones (1, 5), (2) (ones (1,5))) | |
9462 | 60 |
10118 | 61 ** The behavior of library functions `ismatrix', `issquare', and |
62 `issymmetric' has been changed for better consistency. | |
9873 | 63 |
10292 | 64 * The `ismatrix' function now returns true for all numeric, |
65 logical and character 2d or Nd matrices. Previously, `ismatrix' | |
66 returned false if the first or second dimension was zero. | |
67 Hence, `ismatrix ([])' was false, | |
68 while `ismatrix (zeros (1,2,0))' was true. | |
9873 | 69 |
10118 | 70 * The `issquare' function now returns a logical scalar, and is |
71 equivalent to the expression | |
72 | |
73 ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x) | |
74 | |
75 The dimension is no longer returned. As a result, `issquare ([])' | |
76 now yields true. | |
9873 | 77 |
10118 | 78 * The `issymmetric' function now checks for symmetry instead of |
79 hermitianness. For the latter, ishermitian was created. Also, | |
80 logical scalar is returned rather than the dimension, so | |
81 `issymmetric ([])' is now true. | |
9873 | 82 |
10118 | 83 ** Function handles are now aware of overloaded functions. If a |
84 function is overloaded, the handle determines at the time of its | |
85 reference which function to call. A non-overloaded version does not | |
86 need to exist. | |
9873 | 87 |
10118 | 88 ** Overloading functions for built-in classes (double, int8, cell, |
89 etc.) is now compatible with Matlab. | |
9408 | 90 |
10323 | 91 ** Function handles can now be compared with the == and != operators, |
92 as well as the `isequal' function. | |
93 | |
10118 | 94 ** Performance of concatenation (using []) and the functions `cat', |
95 `horzcat', and `vertcat' has been improved for multidimensional | |
96 arrays. | |
10117 | 97 |
9547 | 98 ** The operation-assignment operators +=, -=, *= and /= now behave more |
10118 | 99 efficiently in certain cases. For instance, if M is a matrix and S a |
100 scalar, then the statement | |
9547 | 101 |
10118 | 102 M += S; |
9547 | 103 |
10118 | 104 will operate on M's data in-place if it is not shared by another |
105 variable, usually increasing both time and memory efficiency. | |
9547 | 106 |
9558 | 107 Only selected common combinations are affected, namely: |
9547 | 108 |
109 matrix += matrix | |
110 matrix -= matrix | |
9558 | 111 matrix .*= matrix |
112 matrix ./= matrix | |
113 | |
9547 | 114 matrix += scalar |
115 matrix -= scalar | |
116 matrix *= scalar | |
117 matrix /= scalar | |
9558 | 118 |
9552 | 119 logical matrix |= logical matrix |
120 logical matrix &= logical matrix | |
9547 | 121 |
10118 | 122 where matrix and scalar belong to the same class. The left-hand |
123 side must be a simple variable reference. | |
9888 | 124 |
10118 | 125 Moreover, when unary operators occur in expressions, Octave will |
126 also try to do the operation in-place if it's argument is a | |
127 temporary expresssion. | |
9589 | 128 |
10118 | 129 ** The effect of comparison operators (<, >, <=, and >=) applied to |
130 complex numbers has changed to be consistent with the strict | |
131 ordering defined by the `max', `min', and `sort' functions. More | |
132 specifically, complex numbers are compared by lexicographical | |
133 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
134 parts were compared; this can be trivially achieved by wrapping the | |
135 operands in real(). | |
9547 | 136 |
10118 | 137 ** The automatic simplification of complex computation results has |
138 changed. Octave will now simplify any complex number with a zero | |
139 imaginary part or any complex matrix with all elements having zero | |
140 imaginary part to a real value. Previously, this was done only for | |
141 positive zeros. Note that the behavior of the complex function is | |
142 unchanged and it still produces a complex value even if the | |
143 imaginary part is zero. | |
9826 | 144 |
10118 | 145 ** As a side effect of code refactoring in liboctave, the binary |
146 logical operations are now more easily amenable to compiler | |
147 optimizations and are thus significantly faster. | |
9595 | 148 |
10118 | 149 ** Octave now allows user-defined `subsasgn' methods to optimize out |
150 redundant copies. For more information, see the manual. | |
9595 | 151 |
10118 | 152 ** More efficient matrix division handling. Octave is now able to |
153 handle the expressions | |
9664 | 154 |
10118 | 155 M' \ V |
156 M.' \ V | |
157 V / M | |
9664 | 158 |
10118 | 159 (M is a matrix and V is a vector) more efficiently in certain cases. |
160 In particular, if M is triangular, all three expressions will be | |
161 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
162 flags. Previously, all three expressions required a physical | |
163 transpose of M. | |
9664 | 164 |
10118 | 165 ** More efficient handling of certain mixed real-complex matrix |
166 operations. For instance, if RM is a real matrix and CM a complex | |
167 matrix, | |
9664 | 168 |
10118 | 169 RM * CM |
9664 | 170 |
171 can now be evaluated either as | |
172 | |
173 complex (RM * real (CM), RM * imag (CM)) | |
174 | |
175 or as | |
176 | |
177 complex (RM) * CM, | |
178 | |
10118 | 179 depending on the dimensions. The first form requires more temporaries |
180 and copying, but halves the FLOP count, which normally brings better | |
181 performance if RM has enough rows. Previously, the second form was | |
182 always used. | |
9664 | 183 |
184 Matrix division is similarly affected. | |
185 | |
10118 | 186 ** More efficient handling of triangular matrix factors returned from |
187 factorizations. The functions for computing QR, LU and Cholesky | |
188 factorizations will now automatically return the triangular matrix | |
189 factors with proper internal matrix_type set, so that it won't need | |
190 to be computed when the matrix is used for division. | |
9717 | 191 |
10118 | 192 ** The built-in `sum' function now handles the non-native summation |
193 (i.e., double precision sum of single or integer inputs) more | |
194 efficiently, avoiding a temporary conversion of the whole input | |
195 array to doubles. Further, `sum' can now accept an extra option | |
196 argument, using a compensated summation algorithm rather than a | |
197 straightforward sum, which significantly improves precision if lots | |
198 of cancellation occurs in the summation. | |
9717 | 199 |
10118 | 200 ** The built-in `bsxfun' function now uses optimized code for certain |
201 cases where built-in operator handles are passed in. Namely, the | |
202 optimizations concern the operators `plus', `minus', `times', | |
203 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
204 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
205 functions `min' and `max'. Optimizations only apply when both | |
206 operands are of the same built-in class. Mixed real/complex and | |
207 single/double operations will first convert both operands to a | |
208 common type. | |
9745 | 209 |
10118 | 210 ** The `strfind' and `strrep' functions now have compiled |
211 implementations, facilitating significantly more efficient searching | |
212 and replacing in strings, especially with longer patterns. The code | |
213 of `strcat' has been vectorized and is now much more efficient when | |
214 many strings are concatenated. The `strcmpi' and `strncmpi' | |
215 functions are now built-in functions, providing better performance. | |
10208 | 216 |
217 ** Matlab-style ignoring input and output function arguments using tilde (~) | |
218 is now supported. For more details, consult the manual. | |
10233 | 219 |
220 ** The list datatype, deprecated since the introduction of cells, has been removed. | |
10276 | 221 |
222 ** The accumarray function has been optimized and is now significantly faster | |
223 in certain important cases. | |
10054 | 224 |
10292 | 225 ** The behavior of isreal and isnumeric functions was changed to be more |
226 Matlab-compatible. | |

6329 | 287 |
8885 | 288 ** The Control, Finance and Quaternion functions have been removed. |
289 | |
290 These functions are now available as separate packages from | |
291 | |
292 http://octave.sourceforge.net/packages.html | |
293 | |
294 and can be reinstalled using the Octave package manager (see | |
295 the pkg function). | |
296 | |
297 ** Specific sparse matrix functions removed. | |
298 | |
299 The following functions, which handled only sparse matrices have | |
300 been removed. Instead of calling these functions directly, you | |
301 should use the corresponding function without the "sp" prefix. | |

307 spcumprod spinv spmin | |
308 | |
309 ** Improvements to the debugger. | |
310 | |
311 The interactive debugging features have been improved. Stopping | |
312 on statements with dbstop should work correctly now. Stepping | |
313 into and over functions, and stepping one statement at a time | |
314 (with dbstep) now works. Moving up and down the call stack with | |
315 dbup and dbdown now works. The dbstack function is now available | |
316 to print the current function call stack. The new dbquit function | |
317 is available to exit the debugging mode. | |
318 | |
319 ** Improved traceback error messages. | |
320 | |

327 |
8737 | 328 Octave now includes OOP features and the user can create their own |
329 class objects and overloaded functions and operators. For | |
330 example, all methods of a class called "myclass" will be found in | |
331 a directory "@myclass" on the users path. The class specific | |
332 versions of functions and operators take precedence over the | |
333 generic versions of these functions. | |
334 | |
335 New functions related to OOP include | |
7189 | 336 |
8737 | 337 class inferiorto isobject loadobj methods superiorto |
338 | |
339 See the Octave manual for more details. | |
7038 | 340 |
8747 | 341 ** Parsing of Command-style Functions. |
342 | |
343 Octave now parses command-style functions without needing to first | |
344 declare them with "mark_as_command". The rules for recognizing a | |
345 command-style function calls are | |
346 | |
347 * A command must appear as the first word in a statement, | |
348 followed by a space. | |
349 | |
350 * The first character after the space must not be '=' or '(' | |
351 | |
352 * The next token after the space must not look like a binary | |
353 operator. | |
354 | |
355 These rules should be mostly compatible with the way Matlab parses | |
356 command-style function calls and allow users to define commands in | |
357 .m files without having to mark them as commands. | |
358 | |
359 Note that previous versions of Octave allowed expressions like | |
360 | |
361 x = load -text foo.dat | |
362 | |
363 but an expression like this will now generate a parse error. In | |
364 order to assign the value returned by a function to a variable, | |
365 you must use the normal function call syntax: | |
366 | |
367 x = load ("-text", "foo.dat"); | |
368 | |
8737 | 369 ** Block comments. |
370 | |
8747 | 371 Commented code can be between matching "#{" and "#}" or "%{" and |
372 "%}" markers, even if the commented code spans several line. This | |
373 allows blocks code to be commented, without needing to comment | |
374 each line. For example, | |
5814 | 375 |
8747 | 376 function [s, t] = func (x, y) |
377 s = 2 * x; | |
378 #{ | |
379 s *= y; | |
380 t = y + x; | |
381 #} | |

400 ones (2, 2, "single") | |
401 zeros (2, 2, "single") | |
402 eye (2, 2, "single") | |
403 Inf (2, 2, "single") | |
404 NaN (2, 2, "single") | |
405 NA (2, 2, "single") | |
7279 | 406 |
8737 | 407 all create single precision variables. For compatibility with |
408 Matlab, mixed double/single precision operators and functions | |
409 return single precision types. | |

425 conversions between cells, structs and cs-lists. This usually reduces |
8755 | 426 both time and memory consumption. |
9128 | 427 Also, Octave will now attempt to detect and optimize usage of a vector |
428 as a stack, when elements are being repeatedly inserted at/removed from | |
429 the end of the vector. | |
8755 | 430 |
8738 | 431 ** Improved performance for reduction operations. |
432 | |
8755 | 433 The performance of the sum, prod, sumsq, cumsum, cumprod, any, all, |
434 max and min functions has been significantly improved. | |
8738 | 435 |
9006 | 436 ** Sorting and searching. |
437 | |
438 The performance of sort has been improved, especially when sorting | |
439 indices are requested. An efficient built-in issorted implementation | |
440 was added. sortrows now uses a more efficient algorithm, especially | |
441 in the homegeneous case. lookup is now a built-in function performing | |
442 a binary search, optimized for long runs of close elements. Lookup | |
443 also works with cell arrays of strings. | |
444 | |
445 ** Range arithmetics | |
446 | |
447 For some operations on ranges, Octave will attempt to keep the result as a | |
448 range. These include negation, adding a scalar, subtracting a scalar, and | |
449 multiplying by a scalar. Ranges with zero increment are allowed and can be | |
450 constructed using the built-in function `ones'. | |
451 | |
452 ** Various performance improvements. | |
453 | |
454 Performance of a number of other built-in operations and functions was | |
455 improved, including: | |
456 | |
457 * logical operations | |
458 * comparison operators | |
459 * element-wise power | |
460 * accumarray | |
461 * cellfun | |
462 * isnan | |
463 * isinf | |
464 * isfinite | |
465 * nchoosek | |
466 * repmat | |
467 * strcmp | |
468 | |
8737 | 469 ** 64-bit integer arithmetic. |
470 | |
471 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
472 supported, with saturation semantics like the other integer types. | |
473 Performance of most integer arithmetic operations has been | |
474 improved by using integer arithmetic directly. Previously, Octave | |
475 performed integer math with saturation semantics by converting the | |
476 operands to double precision, performing the operation, and then | |
477 converting the result back to an integer value, truncating if | |
478 necessary. | |
479 | |
8885 | 480 ** Diagonal and permutation matrices. |
481 | |
482 The interpreter can now treat diagonal and permutation matrices as | |
483 special objects that store only the non-zero elements, rather than | |
484 general full matrices. Therefore, it is now possible to construct | |
485 and use these matrices in linear algebra without suffering a | |
486 performance penalty due to storing large numbers of zero elements. | |
487 | |
488 ** Improvements to fsolve. | |
489 | |
490 The fsolve function now accepts an option structure argument (see | |
491 also the optimset function). The INFO values returned from fsolve | |
492 have changed to be compatible with Matlab's fsolve function. | |
493 Additionally, fsolve is now able to solve overdetermined systems, | |
494 complex-differentiable complex systems, systems with a sparse | |
495 jacobian and can work in single precision if given single precision | |

501 matrix in a single call, as well as general matrix p-norms. | |
502 | |
503 ** New functions for computing some eigenvalues or singular values. | |
504 | |
505 The eigs and svds functions have been included in Octave. These | |
506 functions require the ARPACK library (now distributed under a | |
