| 10118 | 234 ** The `lookup' function was extended to be more useful for |
| 235 general-purpose binary searching. Using this improvement, the | |
| 236 ismember function was rewritten for significantly better | |
| 237 performance. | |
| 9352 | 238 |
| 239 ** Real, integer and logical matrices, when used in indexing, will now | |
| 240 cache the internal index_vector value (zero-based indices) when | |
| 241 successfully used as indices, eliminating the conversion penalty for | |
| 10118 | 242 subsequent indexing by the same matrix. In particular, this means it |
| 243 is no longer needed to avoid repeated indexing by logical arrays | |
| 244 using find for performance reasons. | |
| 9888 | 245 |
| 10118 | 246 ** Logical matrices are now treated more efficiently when used as |
| 247 indices. Octave will keep the index as a logical mask unless the | |
| 248 ratio of true elements is small enough, using a specialized | |
| 249 code. Previously, all logical matrices were always first converted | |
| 250 to index vectors. This results in savings in both memory and | |
| 251 computing time. | |
| 9480 | 252 |
| 10118 | 253 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
| 254 functions for better performance. These functions are now faster, | |
| 255 can deliver more economized results for ranges, and can reuse the | |
| 256 index cache mechanism described in previous paragraph. | |
| 257 | |
| 258 ** The built-in function equivalents to associative operators (`plus', | |
| 259 `times', `mtimes', `and', and `or') have been extended to accept | |
| 260 multiple arguments. This is especially useful for summing | |
| 261 (multiplying, etc.) lists of objects (of possibly distinct types): | |
| 9408 | 262 |
| 9449 | 263 matrix_sum = plus (matrix_list{:}); |
| 264 | |
| 10118 | 265 ** An FTP object type based on libcurl has been implemented. These |
| 266 objects allow ftp connections, downloads and uploads to be | |
| 267 managed. For example, | |
| 9880 | 268 |
| 10118 | 269 fp = ftp ("ftp.octave.org); |
| 270 cd (fp, "gnu/octave"); | |
| 271 mget (fp, "octave-3.2.3.tar.bz2"); | |
| 272 close (fp); | |
| 9880 | 273 |
| 10118 | 274 ** The default behavior of `assert (observed, expected)' has been |
| 275 relaxed to employ less strict checking that does not require the | |
| 276 internals of the values to match. This avoids previously valid | |
| 277 tests from breaking due to new internal classes introduced in future | |
| 278 Octave versions. | |
| 9449 | 279 |
| 280 For instance, all of these assertions were true in Octave 3.0.x | |
| 281 but false in 3.2.x due to new optimizations and improvements: | |
| 282 | |
| 283 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
| 284 assert (zeros (0, 0), []) | |
| 285 assert (2*ones (1, 5), (2) (ones (1,5))) | |
| 9462 | 286 |
| 10118 | 287 ** The behavior of library functions `ismatrix', `issquare', and |
| 288 `issymmetric' has been changed for better consistency. | |
| 9873 | 289 |
| 10292 | 290 * The `ismatrix' function now returns true for all numeric, |

291 logical and character 2-D or N-D matrices. Previously, `ismatrix' |
| 10292 | 292 returned false if the first or second dimension was zero. |
| 293 Hence, `ismatrix ([])' was false, | |
| 294 while `ismatrix (zeros (1,2,0))' was true. | |
| 9873 | 295 |
| 10118 | 296 * The `issquare' function now returns a logical scalar, and is |
| 297 equivalent to the expression | |
| 298 | |
| 299 ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x) | |
| 300 | |
| 301 The dimension is no longer returned. As a result, `issquare ([])' | |
| 302 now yields true. | |

| 10118 | 304 * The `issymmetric' function now checks for symmetry instead of |

305 Hermitianness. For the latter, ishermitian was created. Also, |
| 10118 | 306 logical scalar is returned rather than the dimension, so |
| 307 `issymmetric ([])' is now true. | |
| 9873 | 308 |
| 10118 | 309 ** Function handles are now aware of overloaded functions. If a |
| 310 function is overloaded, the handle determines at the time of its | |
| 311 reference which function to call. A non-overloaded version does not | |
| 312 need to exist. | |
| 9873 | 313 |
| 10118 | 314 ** Overloading functions for built-in classes (double, int8, cell, |
| 315 etc.) is now compatible with Matlab. | |
| 9408 | 316 |
| 10323 | 317 ** Function handles can now be compared with the == and != operators, |
| 318 as well as the `isequal' function. | |
| 319 | |
| 10118 | 320 ** Performance of concatenation (using []) and the functions `cat', |
| 321 `horzcat', and `vertcat' has been improved for multidimensional | |
| 322 arrays. | |
| 10117 | 323 |
| 9547 | 324 ** The operation-assignment operators +=, -=, *= and /= now behave more |
| 10118 | 325 efficiently in certain cases. For instance, if M is a matrix and S a |
| 326 scalar, then the statement | |
| 9547 | 327 |
| 10118 | 328 M += S; |
| 9547 | 329 |
| 10118 | 330 will operate on M's data in-place if it is not shared by another |
| 331 variable, usually increasing both time and memory efficiency. | |
| 9547 | 332 |
| 9558 | 333 Only selected common combinations are affected, namely: |
| 9547 | 334 |
| 335 matrix += matrix | |
| 336 matrix -= matrix | |
| 9558 | 337 matrix .*= matrix |
| 338 matrix ./= matrix | |
| 339 | |
| 9547 | 340 matrix += scalar |
| 341 matrix -= scalar | |
| 342 matrix *= scalar | |
| 343 matrix /= scalar | |
| 9558 | 344 |
| 9552 | 345 logical matrix |= logical matrix |
| 346 logical matrix &= logical matrix | |
| 9547 | 347 |
| 10118 | 348 where matrix and scalar belong to the same class. The left-hand |
| 349 side must be a simple variable reference. | |
| 9888 | 350 |
| 10118 | 351 Moreover, when unary operators occur in expressions, Octave will |
| 352 also try to do the operation in-place if it's argument is a | |

353 temporary expression. |
| 9589 | 354 |
| 10118 | 355 ** The effect of comparison operators (<, >, <=, and >=) applied to |
| 356 complex numbers has changed to be consistent with the strict | |
| 357 ordering defined by the `max', `min', and `sort' functions. More | |
| 358 specifically, complex numbers are compared by lexicographical | |
| 359 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
| 360 parts were compared; this can be trivially achieved by wrapping the | |
| 361 operands in real(). | |
| 9547 | 362 |
| 10118 | 363 ** The automatic simplification of complex computation results has |
| 364 changed. Octave will now simplify any complex number with a zero | |
| 365 imaginary part or any complex matrix with all elements having zero | |
| 366 imaginary part to a real value. Previously, this was done only for | |
| 367 positive zeros. Note that the behavior of the complex function is | |
| 368 unchanged and it still produces a complex value even if the | |
| 369 imaginary part is zero. | |
| 9826 | 370 |
| 10118 | 371 ** As a side effect of code refactoring in liboctave, the binary |
| 372 logical operations are now more easily amenable to compiler | |
| 373 optimizations and are thus significantly faster. | |
| 9595 | 374 |
| 10118 | 375 ** Octave now allows user-defined `subsasgn' methods to optimize out |
| 376 redundant copies. For more information, see the manual. | |

| 10118 | 379 handle the expressions |

383 V / M |
| 9664 | 384 |
| 10118 | 385 (M is a matrix and V is a vector) more efficiently in certain cases. |
| 386 In particular, if M is triangular, all three expressions will be | |
| 387 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
| 10453 | 388 flags. Previously, all three expressions required a physical |
| 10118 | 389 transpose of M. |
| 9664 | 390 |
| 10118 | 391 ** More efficient handling of certain mixed real-complex matrix |
| 392 operations. For instance, if RM is a real matrix and CM a complex | |
| 393 matrix, | |
| 9664 | 394 |
| 10118 | 395 RM * CM |
| 9664 | 396 |
| 397 can now be evaluated either as | |
| 398 | |
| 399 complex (RM * real (CM), RM * imag (CM)) | |
| 400 | |
| 401 or as | |
| 402 | |
| 403 complex (RM) * CM, | |
| 404 | |
| 10453 | 405 depending on the dimensions. The first form requires more |
| 406 temporaries and copying, but halves the FLOP count, which normally | |
| 407 brings better performance if RM has enough rows. Previously, the | |
| 408 second form was always used. | |
| 9664 | 409 |
| 11111 | 410 Matrix division is similarly affected. |
| 9664 | 411 |
| 10118 | 412 ** More efficient handling of triangular matrix factors returned from |
| 413 factorizations. The functions for computing QR, LU and Cholesky | |
| 414 factorizations will now automatically return the triangular matrix | |
| 415 factors with proper internal matrix_type set, so that it won't need | |
| 416 to be computed when the matrix is used for division. | |
| 9717 | 417 |
| 10118 | 418 ** The built-in `sum' function now handles the non-native summation |
| 419 (i.e., double precision sum of single or integer inputs) more | |
| 420 efficiently, avoiding a temporary conversion of the whole input | |
| 421 array to doubles. Further, `sum' can now accept an extra option | |
| 422 argument, using a compensated summation algorithm rather than a | |
| 423 straightforward sum, which significantly improves precision if lots | |
| 424 of cancellation occurs in the summation. | |
| 9717 | 425 |
| 10118 | 426 ** The built-in `bsxfun' function now uses optimized code for certain |
| 427 cases where built-in operator handles are passed in. Namely, the | |
| 428 optimizations concern the operators `plus', `minus', `times', | |
| 429 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
| 430 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
| 431 functions `min' and `max'. Optimizations only apply when both | |
| 432 operands are of the same built-in class. Mixed real/complex and | |
| 433 single/double operations will first convert both operands to a | |
| 434 common type. | |
| 9745 | 435 |
| 10118 | 436 ** The `strfind' and `strrep' functions now have compiled |
| 437 implementations, facilitating significantly more efficient searching | |
| 438 and replacing in strings, especially with longer patterns. The code | |
| 439 of `strcat' has been vectorized and is now much more efficient when | |
| 440 many strings are concatenated. The `strcmpi' and `strncmpi' | |
| 441 functions are now built-in functions, providing better performance. | |

446 has been removed. |
| 10208 | 447 |
| 10453 | 448 ** Matlab-style ignoring input and output function arguments using |
| 11111 | 449 tilde (~) is now supported. Ignored output arguments may be |
| 450 detected from a function using the built-in function `isargout'. | |
| 451 For more details, consult the manual. | |
| 10886 | 452 |
| 10453 | 453 ** The list datatype, deprecated since the introduction of cells, has |
| 454 been removed. | |
| 10276 | 455 |
| 10453 | 456 ** The accumarray function has been optimized and is now significantly |
| 457 faster in certain important cases. | |
| 10054 | 458 |
| 10292 | 459 ** The behavior of isreal and isnumeric functions was changed to be more |
| 460 Matlab-compatible. | |
| 461 | |
| 10406 | 462 ** The integer math & conversion warnings (Octave:int-convert-nan, |
| 463 Octave:int-convert-non-int-val, Octave:int-convert-overflow, | |
| 11111 | 464 Octave:int-math-overflow) have been removed. |
| 10406 | 465 |
| 10453 | 466 ** rem and mod are now built-in functions. They also handle integer |
| 467 types efficiently using integer arithmetic. | |
| 10437 | 468 |
| 10536 | 469 ** Sparse indexing and indexed assignment has been mostly rewritten. |
| 470 Since Octave uses compressed column storage for sparse matrices, | |
| 471 major attention is devoted to operations manipulating whole columns. | |
| 472 Such operations are now significantly faster, as well as some other | |
| 473 important cases. | |
| 474 | |
| 475 Further, it is now possible to pre-allocate a sparse matrix and | |
| 476 subsequently fill it by assignments, provided they meet certain | |
| 477 conditions. For more information, consult the `spalloc' function, | |
| 478 which is no longer a mere dummy. Consequently, nzmax and nnz are no | |
| 11111 | 479 longer always equal in Octave. Octave may also produce a matrix |
| 480 with nnz < nzmax as a result of other operations, so you should | |
| 481 consistently use nnz unless you really want to use nzmax (i.e. the | |
| 482 space allocated for nonzero elements). | |
| 10536 | 483 |
| 484 Sparse concatenation is also affected, and concatenating sparse | |
| 485 matrices, especially larger collections, is now significantly more | |
| 11111 | 486 efficient. This applies to both the [] operator and the |
| 10536 | 487 cat/vertcat/horzcat functions. |
| 488 | |
| 11111 | 489 ** It is now possible to optionally employ the xGESDD LAPACK drivers |
| 490 for computing the singular value decomposition using svd(), instead | |
| 491 of the default xGESVD, using the configuration pseudo-variable | |
| 492 svd_driver. The xGESDD driver can be up to 6x times faster when | |
| 493 singular vectors are requested, but is reported to be somewhat less | |
| 10639 | 494 robust on highly ill-conditioned matrices. |
| 495 | |
| 496 ** Configuration pseudo-variables, such as page_screen_output or | |
| 497 confirm_recursive_rmdir (or the above mentioned svd_driver), now | |
| 498 accept a "local" option as second argument, requesting the change | |

712 __gnuplot_show__, __gnuplot_replot__, __gnuplot_splot__, |
| 8737 | 713 __gnuplot_save_data__ and __gnuplot_send_inline_data__ have been |
| 714 removed from Octave. These function were incompatible with the | |
| 715 high level graphics handle code. | |
| 6329 | 716 |
| 8885 | 717 ** The Control, Finance and Quaternion functions have been removed. |
| 718 | |
| 719 These functions are now available as separate packages from | |
| 720 | |
| 721 http://octave.sourceforge.net/packages.html | |
| 722 | |
| 723 and can be reinstalled using the Octave package manager (see | |
| 724 the pkg function). | |
| 725 | |
| 726 ** Specific sparse matrix functions removed. | |
| 727 | |
| 728 The following functions, which handled only sparse matrices have | |
| 729 been removed. Instead of calling these functions directly, you | |
| 730 should use the corresponding function without the "sp" prefix. | |
| 8737 | 731 |

| 733 spchol spdet splchol spqr | |

| 736 spcumprod spinv spmin | |
| 737 | |
| 738 ** Improvements to the debugger. | |
| 739 | |
| 740 The interactive debugging features have been improved. Stopping | |
| 741 on statements with dbstop should work correctly now. Stepping | |
| 742 into and over functions, and stepping one statement at a time | |
| 743 (with dbstep) now works. Moving up and down the call stack with | |
| 744 dbup and dbdown now works. The dbstack function is now available | |
| 745 to print the current function call stack. The new dbquit function | |
| 746 is available to exit the debugging mode. | |
| 747 | |
| 748 ** Improved traceback error messages. | |
| 749 | |
| 750 Traceback error messages are much more concise and easier to | |
| 751 understand. They now display information about the function call | |
| 752 stack instead of the stack of all statements that were active at | |
| 753 the point of the error. | |

756 |
| 8737 | 757 Octave now includes OOP features and the user can create their own |
| 758 class objects and overloaded functions and operators. For | |
| 759 example, all methods of a class called "myclass" will be found in | |
| 760 a directory "@myclass" on the users path. The class specific | |
| 761 versions of functions and operators take precedence over the | |
| 762 generic versions of these functions. | |
| 763 | |
| 764 New functions related to OOP include | |
| 7189 | 765 |
| 8737 | 766 class inferiorto isobject loadobj methods superiorto |
| 767 | |
| 768 See the Octave manual for more details. | |
| 7038 | 769 |
| 8747 | 770 ** Parsing of Command-style Functions. |
| 771 | |
| 772 Octave now parses command-style functions without needing to first | |
| 773 declare them with "mark_as_command". The rules for recognizing a | |
| 774 command-style function calls are | |
| 775 | |
| 776 * A command must appear as the first word in a statement, | |
| 777 followed by a space. | |
| 778 | |
| 779 * The first character after the space must not be '=' or '(' | |
| 780 | |
| 781 * The next token after the space must not look like a binary | |
| 782 operator. | |
| 783 | |
| 784 These rules should be mostly compatible with the way Matlab parses | |
| 785 command-style function calls and allow users to define commands in | |
| 786 .m files without having to mark them as commands. | |
| 787 | |
| 788 Note that previous versions of Octave allowed expressions like | |
| 789 | |
| 790 x = load -text foo.dat | |
| 791 | |
| 792 but an expression like this will now generate a parse error. In | |
| 793 order to assign the value returned by a function to a variable, | |
| 794 you must use the normal function call syntax: | |
| 795 | |
| 796 x = load ("-text", "foo.dat"); | |
| 797 | |
| 8737 | 798 ** Block comments. |
| 799 | |
| 8747 | 800 Commented code can be between matching "#{" and "#}" or "%{" and |
| 801 "%}" markers, even if the commented code spans several line. This | |
| 802 allows blocks code to be commented, without needing to comment | |
| 803 each line. For example, | |
| 5814 | 804 |
| 8747 | 805 function [s, t] = func (x, y) |
| 806 s = 2 * x; | |
| 807 #{ | |
| 808 s *= y; | |
| 809 t = y + x; | |
| 810 #} | |

866 conversions between cells, structs and cs-lists. This usually reduces |
| 8755 | 867 both time and memory consumption. |

882 efficient algorithm, especially in the homogeneous case. The lookup |
| 10453 | 883 function is now a built-in function performing a binary search, |

| 9006 | 886 |
| 887 ** Range arithmetics | |
| 888 | |
| 10453 | 889 For some operations on ranges, Octave will attempt to keep the |

| 891 subtracting a scalar, and multiplying by a scalar. Ranges with zero | |

| 898 was improved, including: | |
| 9006 | 899 |
| 900 * logical operations | |
| 901 * comparison operators | |
| 902 * element-wise power | |
| 903 * accumarray | |
| 904 * cellfun | |
| 905 * isnan | |
| 906 * isinf | |
| 907 * isfinite | |
| 908 * nchoosek | |
| 909 * repmat | |
| 910 * strcmp | |
| 911 | |
| 8737 | 912 ** 64-bit integer arithmetic. |
| 913 | |
| 914 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
| 915 supported, with saturation semantics like the other integer types. | |
| 916 Performance of most integer arithmetic operations has been | |
| 917 improved by using integer arithmetic directly. Previously, Octave | |
| 918 performed integer math with saturation semantics by converting the | |
| 919 operands to double precision, performing the operation, and then | |
| 920 converting the result back to an integer value, truncating if | |
| 921 necessary. | |
| 922 | |
| 8885 | 923 ** Diagonal and permutation matrices. |
| 924 | |
| 925 The interpreter can now treat diagonal and permutation matrices as | |
| 926 special objects that store only the non-zero elements, rather than | |
| 927 general full matrices. Therefore, it is now possible to construct | |
| 928 and use these matrices in linear algebra without suffering a | |
| 929 performance penalty due to storing large numbers of zero elements. | |
| 930 | |
| 931 ** Improvements to fsolve. | |
| 932 | |
| 933 The fsolve function now accepts an option structure argument (see | |
| 934 also the optimset function). The INFO values returned from fsolve | |
| 935 have changed to be compatible with Matlab's fsolve function. | |
| 936 Additionally, fsolve is now able to solve overdetermined systems, | |
| 937 complex-differentiable complex systems, systems with a sparse | |
| 938 jacobian and can work in single precision if given single precision | |

| 8885 | 940 |
| 8737 | 941 ** Improvements to the norm function. |
| 942 | |
| 943 The norm function is now able to compute row or column norms of a | |
| 944 matrix in a single call, as well as general matrix p-norms. | |
| 945 | |
| 946 ** New functions for computing some eigenvalues or singular values. | |
| 947 | |
| 948 The eigs and svds functions have been included in Octave. These | |
| 949 functions require the ARPACK library (now distributed under a | |
| 950 GPL-compatible license). | |
| 951 | |
| 952 ** New QR and Cholesky factorization updating functions. | |

| 8885 | 993 ** Changes to strcat. |
| 994 | |
| 995 The strcat function is now compatible with Matlab's strcat | |
| 996 function, which removes trailing whitespace when concatenating | |
| 997 character strings. For example | |
| 998 | |
| 999 strcat ('foo ', 'bar') | |
| 1000 ==> 'foobar' | |
| 1001 | |
| 1002 The new function cstrcat provides the previous behavior of | |

1007 The help system has been mostly re-implemented in .m files to make |
| 8885 | 1008 it easier to modify. Performance of the lookfor function has been |
| 1009 greatly improved by caching the help text from all functions that | |
| 1010 are distributed with Octave. The pkg function has been modified | |
| 1011 to generate cache files for external packages when they are | |
| 1012 installed. | |
