| 10118 | 312 ** The `lookup' function was extended to be more useful for |
| 313 general-purpose binary searching. Using this improvement, the | |
| 314 ismember function was rewritten for significantly better | |
| 315 performance. | |
| 9352 | 316 |
| 317 ** Real, integer and logical matrices, when used in indexing, will now | |
| 318 cache the internal index_vector value (zero-based indices) when | |
| 319 successfully used as indices, eliminating the conversion penalty for | |
| 10118 | 320 subsequent indexing by the same matrix. In particular, this means it |
| 321 is no longer needed to avoid repeated indexing by logical arrays | |
| 322 using find for performance reasons. | |
| 9888 | 323 |
| 10118 | 324 ** Logical matrices are now treated more efficiently when used as |
| 325 indices. Octave will keep the index as a logical mask unless the | |
| 326 ratio of true elements is small enough, using a specialized | |
| 327 code. Previously, all logical matrices were always first converted | |
| 328 to index vectors. This results in savings in both memory and | |
| 329 computing time. | |
| 9480 | 330 |
| 10118 | 331 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
| 332 functions for better performance. These functions are now faster, | |
| 333 can deliver more economized results for ranges, and can reuse the | |
| 334 index cache mechanism described in previous paragraph. | |
| 335 | |
| 336 ** The built-in function equivalents to associative operators (`plus', | |
| 337 `times', `mtimes', `and', and `or') have been extended to accept | |
| 338 multiple arguments. This is especially useful for summing | |
| 339 (multiplying, etc.) lists of objects (of possibly distinct types): | |
| 9408 | 340 |
| 9449 | 341 matrix_sum = plus (matrix_list{:}); |
| 342 | |
| 10118 | 343 ** An FTP object type based on libcurl has been implemented. These |
| 344 objects allow ftp connections, downloads and uploads to be | |
| 345 managed. For example, | |
| 9880 | 346 |
| 10118 | 347 fp = ftp ("ftp.octave.org); |
| 348 cd (fp, "gnu/octave"); | |
| 349 mget (fp, "octave-3.2.3.tar.bz2"); | |
| 350 close (fp); | |
| 9880 | 351 |
| 10118 | 352 ** The default behavior of `assert (observed, expected)' has been |
| 353 relaxed to employ less strict checking that does not require the | |
| 354 internals of the values to match. This avoids previously valid | |
| 355 tests from breaking due to new internal classes introduced in future | |
| 356 Octave versions. | |
| 9449 | 357 |
| 358 For instance, all of these assertions were true in Octave 3.0.x | |
| 359 but false in 3.2.x due to new optimizations and improvements: | |
| 360 | |
| 361 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
| 362 assert (zeros (0, 0), []) | |
| 363 assert (2*ones (1, 5), (2) (ones (1,5))) | |
| 9462 | 364 |
| 10118 | 365 ** The behavior of library functions `ismatrix', `issquare', and |
| 366 `issymmetric' has been changed for better consistency. | |

369 logical and character 2-D or N-D matrices. Previously, `ismatrix' |
| 10292 | 370 returned false if the first or second dimension was zero. |
| 371 Hence, `ismatrix ([])' was false, | |
| 372 while `ismatrix (zeros (1,2,0))' was true. | |

383 Hermitianness. For the latter, ishermitian was created. Also, |
| 10118 | 384 logical scalar is returned rather than the dimension, so |
| 385 `issymmetric ([])' is now true. | |
| 9873 | 386 |
| 10118 | 387 ** Function handles are now aware of overloaded functions. If a |
| 388 function is overloaded, the handle determines at the time of its | |
| 389 reference which function to call. A non-overloaded version does not | |
| 390 need to exist. | |
| 9873 | 391 |
| 10118 | 392 ** Overloading functions for built-in classes (double, int8, cell, |
| 393 etc.) is now compatible with Matlab. | |
| 9408 | 394 |
| 10323 | 395 ** Function handles can now be compared with the == and != operators, |
| 396 as well as the `isequal' function. | |
| 397 | |
| 10118 | 398 ** Performance of concatenation (using []) and the functions `cat', |
| 399 `horzcat', and `vertcat' has been improved for multidimensional | |
| 400 arrays. | |
| 10117 | 401 |
| 9547 | 402 ** The operation-assignment operators +=, -=, *= and /= now behave more |
| 10118 | 403 efficiently in certain cases. For instance, if M is a matrix and S a |
| 404 scalar, then the statement | |
| 9547 | 405 |
| 10118 | 406 M += S; |
| 9547 | 407 |
| 10118 | 408 will operate on M's data in-place if it is not shared by another |
| 409 variable, usually increasing both time and memory efficiency. | |
| 9547 | 410 |
| 9558 | 411 Only selected common combinations are affected, namely: |
| 9547 | 412 |
| 413 matrix += matrix | |
| 414 matrix -= matrix | |
| 9558 | 415 matrix .*= matrix |
| 416 matrix ./= matrix | |
| 417 | |
| 9547 | 418 matrix += scalar |
| 419 matrix -= scalar | |
| 420 matrix *= scalar | |
| 421 matrix /= scalar | |
| 9558 | 422 |
| 9552 | 423 logical matrix |= logical matrix |
| 424 logical matrix &= logical matrix | |
| 9547 | 425 |
| 10118 | 426 where matrix and scalar belong to the same class. The left-hand |
| 427 side must be a simple variable reference. | |
| 9888 | 428 |
| 10118 | 429 Moreover, when unary operators occur in expressions, Octave will |
| 430 also try to do the operation in-place if it's argument is a | |

431 temporary expression. |
| 9589 | 432 |
| 10118 | 433 ** The effect of comparison operators (<, >, <=, and >=) applied to |
| 434 complex numbers has changed to be consistent with the strict | |
| 435 ordering defined by the `max', `min', and `sort' functions. More | |
| 436 specifically, complex numbers are compared by lexicographical | |
| 437 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
| 14188 | 438 parts were compared; this can be trivially achieved by converting |
| 439 the operands to real values with the `real' function. | |
| 9547 | 440 |
| 10118 | 441 ** The automatic simplification of complex computation results has |
| 442 changed. Octave will now simplify any complex number with a zero | |
| 443 imaginary part or any complex matrix with all elements having zero | |
| 444 imaginary part to a real value. Previously, this was done only for | |
| 445 positive zeros. Note that the behavior of the complex function is | |
| 446 unchanged and it still produces a complex value even if the | |
| 447 imaginary part is zero. | |
| 9826 | 448 |
| 10118 | 449 ** As a side effect of code refactoring in liboctave, the binary |
| 450 logical operations are now more easily amenable to compiler | |
| 451 optimizations and are thus significantly faster. | |
| 9595 | 452 |
| 10118 | 453 ** Octave now allows user-defined `subsasgn' methods to optimize out |
| 454 redundant copies. For more information, see the manual. | |

461 V / M |
| 9664 | 462 |
| 10118 | 463 (M is a matrix and V is a vector) more efficiently in certain cases. |
| 464 In particular, if M is triangular, all three expressions will be | |
| 465 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
| 10453 | 466 flags. Previously, all three expressions required a physical |
| 10118 | 467 transpose of M. |
| 9664 | 468 |
| 10118 | 469 ** More efficient handling of certain mixed real-complex matrix |
| 470 operations. For instance, if RM is a real matrix and CM a complex | |
| 471 matrix, | |
| 9664 | 472 |
| 10118 | 473 RM * CM |
| 9664 | 474 |
| 475 can now be evaluated either as | |
| 476 | |
| 477 complex (RM * real (CM), RM * imag (CM)) | |
| 478 | |
| 479 or as | |
| 480 | |
| 481 complex (RM) * CM, | |
| 482 | |
| 10453 | 483 depending on the dimensions. The first form requires more |
| 484 temporaries and copying, but halves the FLOP count, which normally | |
| 485 brings better performance if RM has enough rows. Previously, the | |
| 486 second form was always used. | |
| 9664 | 487 |
| 11111 | 488 Matrix division is similarly affected. |
| 9664 | 489 |
| 10118 | 490 ** More efficient handling of triangular matrix factors returned from |
| 491 factorizations. The functions for computing QR, LU and Cholesky | |
| 492 factorizations will now automatically return the triangular matrix | |
| 493 factors with proper internal matrix_type set, so that it won't need | |
| 494 to be computed when the matrix is used for division. | |
| 9717 | 495 |
| 10118 | 496 ** The built-in `sum' function now handles the non-native summation |
| 497 (i.e., double precision sum of single or integer inputs) more | |
| 498 efficiently, avoiding a temporary conversion of the whole input | |
| 499 array to doubles. Further, `sum' can now accept an extra option | |
| 500 argument, using a compensated summation algorithm rather than a | |
| 501 straightforward sum, which significantly improves precision if lots | |
| 502 of cancellation occurs in the summation. | |
| 9717 | 503 |
| 10118 | 504 ** The built-in `bsxfun' function now uses optimized code for certain |
| 505 cases where built-in operator handles are passed in. Namely, the | |
| 506 optimizations concern the operators `plus', `minus', `times', | |
| 507 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
| 508 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
| 509 functions `min' and `max'. Optimizations only apply when both | |
| 510 operands are of the same built-in class. Mixed real/complex and | |
| 511 single/double operations will first convert both operands to a | |
| 512 common type. | |
| 9745 | 513 |
| 10118 | 514 ** The `strfind' and `strrep' functions now have compiled |
| 515 implementations, facilitating significantly more efficient searching | |
| 516 and replacing in strings, especially with longer patterns. The code | |
| 517 of `strcat' has been vectorized and is now much more efficient when | |
| 518 many strings are concatenated. The `strcmpi' and `strncmpi' | |
| 519 functions are now built-in functions, providing better performance. | |

| 10453 | 526 ** Matlab-style ignoring input and output function arguments using |
| 11111 | 527 tilde (~) is now supported. Ignored output arguments may be |
| 528 detected from a function using the built-in function `isargout'. | |
| 529 For more details, consult the manual. | |
| 10886 | 530 |
| 10453 | 531 ** The list datatype, deprecated since the introduction of cells, has |

| 541 Octave:int-convert-non-int-val, Octave:int-convert-overflow, | |

| 10453 | 544 ** rem and mod are now built-in functions. They also handle integer |
| 545 types efficiently using integer arithmetic. | |
| 10437 | 546 |
| 10536 | 547 ** Sparse indexing and indexed assignment has been mostly rewritten. |
| 548 Since Octave uses compressed column storage for sparse matrices, | |
| 549 major attention is devoted to operations manipulating whole columns. | |
| 550 Such operations are now significantly faster, as well as some other | |
| 551 important cases. | |
| 552 | |
| 553 Further, it is now possible to pre-allocate a sparse matrix and | |
| 554 subsequently fill it by assignments, provided they meet certain | |
| 555 conditions. For more information, consult the `spalloc' function, | |
| 556 which is no longer a mere dummy. Consequently, nzmax and nnz are no | |
| 11111 | 557 longer always equal in Octave. Octave may also produce a matrix |
| 558 with nnz < nzmax as a result of other operations, so you should | |

559 consistently use nnz unless you really want to use nzmax (i.e., the |
| 11111 | 560 space allocated for nonzero elements). |
| 10536 | 561 |
| 562 Sparse concatenation is also affected, and concatenating sparse | |
| 563 matrices, especially larger collections, is now significantly more | |
| 11111 | 564 efficient. This applies to both the [] operator and the |
| 10536 | 565 cat/vertcat/horzcat functions. |
| 566 | |
| 11111 | 567 ** It is now possible to optionally employ the xGESDD LAPACK drivers |
| 14188 | 568 for computing the singular value decomposition using svd, instead |
| 11111 | 569 of the default xGESVD, using the configuration pseudo-variable |
| 570 svd_driver. The xGESDD driver can be up to 6x times faster when | |
| 571 singular vectors are requested, but is reported to be somewhat less | |
| 10639 | 572 robust on highly ill-conditioned matrices. |
| 573 | |
| 574 ** Configuration pseudo-variables, such as page_screen_output or | |
| 575 confirm_recursive_rmdir (or the above mentioned svd_driver), now | |

| 819 on statements with dbstop should work correctly now. Stepping | |
| 820 into and over functions, and stepping one statement at a time | |
| 821 (with dbstep) now works. Moving up and down the call stack with | |
| 822 dbup and dbdown now works. The dbstack function is now available | |
| 823 to print the current function call stack. The new dbquit function | |
| 824 is available to exit the debugging mode. | |
| 825 | |
| 826 ** Improved traceback error messages. | |
| 827 | |
| 828 Traceback error messages are much more concise and easier to | |
| 829 understand. They now display information about the function call | |
| 830 stack instead of the stack of all statements that were active at | |
| 831 the point of the error. | |

834 |
| 8737 | 835 Octave now includes OOP features and the user can create their own |
| 836 class objects and overloaded functions and operators. For | |
| 837 example, all methods of a class called "myclass" will be found in | |
| 838 a directory "@myclass" on the users path. The class specific | |
| 839 versions of functions and operators take precedence over the | |
| 840 generic versions of these functions. | |
| 841 | |
| 842 New functions related to OOP include | |
| 7189 | 843 |
| 8737 | 844 class inferiorto isobject loadobj methods superiorto |
| 845 | |
| 846 See the Octave manual for more details. | |
| 7038 | 847 |
| 8747 | 848 ** Parsing of Command-style Functions. |
| 849 | |
| 850 Octave now parses command-style functions without needing to first | |
| 851 declare them with "mark_as_command". The rules for recognizing a | |
| 852 command-style function calls are | |
| 853 | |
| 854 * A command must appear as the first word in a statement, | |
| 855 followed by a space. | |
| 856 | |
| 857 * The first character after the space must not be '=' or '(' | |
| 858 | |
| 859 * The next token after the space must not look like a binary | |
| 860 operator. | |
| 861 | |
| 862 These rules should be mostly compatible with the way Matlab parses | |
| 863 command-style function calls and allow users to define commands in | |
| 864 .m files without having to mark them as commands. | |
| 865 | |
| 866 Note that previous versions of Octave allowed expressions like | |
| 867 | |
| 868 x = load -text foo.dat | |
| 869 | |
| 870 but an expression like this will now generate a parse error. In | |
| 871 order to assign the value returned by a function to a variable, | |
| 872 you must use the normal function call syntax: | |
| 873 | |
| 874 x = load ("-text", "foo.dat"); | |
| 875 | |
| 8737 | 876 ** Block comments. |
| 877 | |
| 8747 | 878 Commented code can be between matching "#{" and "#}" or "%{" and |
| 879 "%}" markers, even if the commented code spans several line. This | |
| 880 allows blocks code to be commented, without needing to comment | |
| 881 each line. For example, | |
| 5814 | 882 |
| 8747 | 883 function [s, t] = func (x, y) |
| 884 s = 2 * x; | |
| 885 #{ | |
| 886 s *= y; | |
| 887 t = y + x; | |
| 888 #} | |

944 conversions between cells, structs and cs-lists. This usually reduces |
| 8755 | 945 both time and memory consumption. |
| 9128 | 946 Also, Octave will now attempt to detect and optimize usage of a vector |
| 947 as a stack, when elements are being repeatedly inserted at/removed from | |
| 948 the end of the vector. | |
| 8755 | 949 |

969 subtracting a scalar, and multiplying by a scalar. Ranges with zero |
| 10453 | 970 increment are allowed and can be constructed using the built-in |
| 971 function `ones'. | |
| 9006 | 972 |
| 973 ** Various performance improvements. | |
| 974 | |
| 10453 | 975 Performance of a number of other built-in operations and functions |
| 976 was improved, including: | |
| 9006 | 977 |
| 978 * logical operations | |
| 979 * comparison operators | |
| 980 * element-wise power | |
| 981 * accumarray | |
| 982 * cellfun | |
| 983 * isnan | |
| 984 * isinf | |
| 985 * isfinite | |
| 986 * nchoosek | |
| 987 * repmat | |
| 988 * strcmp | |
| 989 | |
| 8737 | 990 ** 64-bit integer arithmetic. |
| 991 | |
| 992 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
| 993 supported, with saturation semantics like the other integer types. | |
| 994 Performance of most integer arithmetic operations has been | |
| 995 improved by using integer arithmetic directly. Previously, Octave | |
| 996 performed integer math with saturation semantics by converting the | |
| 997 operands to double precision, performing the operation, and then | |
| 998 converting the result back to an integer value, truncating if | |
| 999 necessary. | |
| 1000 | |
| 8885 | 1001 ** Diagonal and permutation matrices. |
| 1002 | |
| 1003 The interpreter can now treat diagonal and permutation matrices as | |
| 1004 special objects that store only the non-zero elements, rather than | |
| 1005 general full matrices. Therefore, it is now possible to construct | |
| 1006 and use these matrices in linear algebra without suffering a | |
| 1007 performance penalty due to storing large numbers of zero elements. | |
| 1008 | |
| 1009 ** Improvements to fsolve. | |
| 1010 | |
| 1011 The fsolve function now accepts an option structure argument (see | |
| 1012 also the optimset function). The INFO values returned from fsolve | |
| 1013 have changed to be compatible with Matlab's fsolve function. | |
| 1014 Additionally, fsolve is now able to solve overdetermined systems, | |
| 1015 complex-differentiable complex systems, systems with a sparse | |
| 1016 jacobian and can work in single precision if given single precision | |

| 8885 | 1071 ** Changes to strcat. |
| 1072 | |
| 1073 The strcat function is now compatible with Matlab's strcat | |
| 1074 function, which removes trailing whitespace when concatenating | |
| 1075 character strings. For example | |
| 1076 | |
| 1077 strcat ('foo ', 'bar') | |
| 1078 ==> 'foobar' | |
| 1079 | |
| 1080 The new function cstrcat provides the previous behavior of | |
| 1081 Octave's strcat. | |
| 1082 | |
| 1083 ** Improvements to the help functions. | |

1085 The help system has been mostly re-implemented in .m files to make |
| 8885 | 1086 it easier to modify. Performance of the lookfor function has been |
| 1087 greatly improved by caching the help text from all functions that | |
| 1088 are distributed with Octave. The pkg function has been modified | |
| 1089 to generate cache files for external packages when they are | |
| 1090 installed. | |
