Read alpha values from indexed images. Always read indexes from indexed images.
* __magick_read__.cc (read_indexed_images): turn function into template to
remove duplicated loop. Create alpha channel from alpha values colormap.
Skip reading of colormap unless requested. Use fortran_vec to fill the
image instead of indexing the Array<T> with a dim_vector which requires
multiple calls to dim_vector::operator() per iteration.
(__magick_read__): Always read the indexes of an indexed image and not the
RGB or grayscale values when no colormap is requested for output (Matlab
compatibility).
* imread.m: document that an indexed image is always read as such,
independently of the colormap having been requested or not.
* NEWS: add note on the change for reading indexed images.

10118 | 539 ** The `lookup' function was extended to be more useful for |
540 general-purpose binary searching. Using this improvement, the | |
541 ismember function was rewritten for significantly better | |
542 performance. | |
9352 | 543 |
544 ** Real, integer and logical matrices, when used in indexing, will now | |
545 cache the internal index_vector value (zero-based indices) when | |
546 successfully used as indices, eliminating the conversion penalty for | |
10118 | 547 subsequent indexing by the same matrix. In particular, this means it |
548 is no longer needed to avoid repeated indexing by logical arrays | |
549 using find for performance reasons. | |
9888 | 550 |
10118 | 551 ** Logical matrices are now treated more efficiently when used as |
552 indices. Octave will keep the index as a logical mask unless the | |
553 ratio of true elements is small enough, using a specialized | |
554 code. Previously, all logical matrices were always first converted | |
555 to index vectors. This results in savings in both memory and | |
556 computing time. | |
9480 | 557 |
10118 | 558 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
559 functions for better performance. These functions are now faster, | |
560 can deliver more economized results for ranges, and can reuse the | |
561 index cache mechanism described in previous paragraph. | |
562 | |
563 ** The built-in function equivalents to associative operators (`plus', | |
564 `times', `mtimes', `and', and `or') have been extended to accept | |
565 multiple arguments. This is especially useful for summing | |
566 (multiplying, etc.) lists of objects (of possibly distinct types): | |
9408 | 567 |
9449 | 568 matrix_sum = plus (matrix_list{:}); |
569 | |
10118 | 570 ** An FTP object type based on libcurl has been implemented. These |
571 objects allow ftp connections, downloads and uploads to be | |
572 managed. For example, | |
9880 | 573 |
10118 | 574 fp = ftp ("ftp.octave.org); |
575 cd (fp, "gnu/octave"); | |
576 mget (fp, "octave-3.2.3.tar.bz2"); | |
577 close (fp); | |
9880 | 578 |
10118 | 579 ** The default behavior of `assert (observed, expected)' has been |
580 relaxed to employ less strict checking that does not require the | |
581 internals of the values to match. This avoids previously valid | |
582 tests from breaking due to new internal classes introduced in future | |
583 Octave versions. | |
9449 | 584 |
585 For instance, all of these assertions were true in Octave 3.0.x | |
586 but false in 3.2.x due to new optimizations and improvements: | |
587 | |
588 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
589 assert (zeros (0, 0), []) | |
590 assert (2*ones (1, 5), (2) (ones (1,5))) | |
9462 | 591 |
10118 | 592 ** The behavior of library functions `ismatrix', `issquare', and |
593 `issymmetric' has been changed for better consistency. | |

596 logical and character 2-D or N-D matrices. Previously, `ismatrix' |
10292 | 597 returned false if the first or second dimension was zero. |
598 Hence, `ismatrix ([])' was false, | |
599 while `ismatrix (zeros (1,2,0))' was true. | |
9873 | 600 |
10118 | 601 * The `issquare' function now returns a logical scalar, and is |
602 equivalent to the expression | |
603 | |
604 ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x) | |
605 | |
606 The dimension is no longer returned. As a result, `issquare ([])' | |
607 now yields true. | |
9873 | 608 |
10118 | 609 * The `issymmetric' function now checks for symmetry instead of |

610 Hermitianness. For the latter, ishermitian was created. Also, |
10118 | 611 logical scalar is returned rather than the dimension, so |
612 `issymmetric ([])' is now true. | |
9873 | 613 |
10118 | 614 ** Function handles are now aware of overloaded functions. If a |
615 function is overloaded, the handle determines at the time of its | |
616 reference which function to call. A non-overloaded version does not | |
617 need to exist. | |
9873 | 618 |
10118 | 619 ** Overloading functions for built-in classes (double, int8, cell, |
620 etc.) is now compatible with Matlab. | |
9408 | 621 |
10323 | 622 ** Function handles can now be compared with the == and != operators, |
623 as well as the `isequal' function. | |
624 | |
10118 | 625 ** Performance of concatenation (using []) and the functions `cat', |
626 `horzcat', and `vertcat' has been improved for multidimensional | |
627 arrays. | |
10117 | 628 |
9547 | 629 ** The operation-assignment operators +=, -=, *= and /= now behave more |
10118 | 630 efficiently in certain cases. For instance, if M is a matrix and S a |
631 scalar, then the statement | |
9547 | 632 |
10118 | 633 M += S; |
9547 | 634 |
10118 | 635 will operate on M's data in-place if it is not shared by another |
636 variable, usually increasing both time and memory efficiency. | |
9547 | 637 |
9558 | 638 Only selected common combinations are affected, namely: |
9547 | 639 |
640 matrix += matrix | |
641 matrix -= matrix | |
9558 | 642 matrix .*= matrix |
643 matrix ./= matrix | |
644 | |
9547 | 645 matrix += scalar |
646 matrix -= scalar | |
647 matrix *= scalar | |
648 matrix /= scalar | |
9558 | 649 |
9552 | 650 logical matrix |= logical matrix |
651 logical matrix &= logical matrix | |
9547 | 652 |
10118 | 653 where matrix and scalar belong to the same class. The left-hand |
654 side must be a simple variable reference. | |
9888 | 655 |
10118 | 656 Moreover, when unary operators occur in expressions, Octave will |
657 also try to do the operation in-place if it's argument is a | |

658 temporary expression. |
9589 | 659 |
10118 | 660 ** The effect of comparison operators (<, >, <=, and >=) applied to |
661 complex numbers has changed to be consistent with the strict | |
662 ordering defined by the `max', `min', and `sort' functions. More | |
663 specifically, complex numbers are compared by lexicographical | |
664 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
14188 | 665 parts were compared; this can be trivially achieved by converting |
666 the operands to real values with the `real' function. | |
9547 | 667 |
10118 | 668 ** The automatic simplification of complex computation results has |
669 changed. Octave will now simplify any complex number with a zero | |
670 imaginary part or any complex matrix with all elements having zero | |
671 imaginary part to a real value. Previously, this was done only for | |
672 positive zeros. Note that the behavior of the complex function is | |
673 unchanged and it still produces a complex value even if the | |
674 imaginary part is zero. | |
9826 | 675 |
10118 | 676 ** As a side effect of code refactoring in liboctave, the binary |
677 logical operations are now more easily amenable to compiler | |
678 optimizations and are thus significantly faster. | |
9595 | 679 |
10118 | 680 ** Octave now allows user-defined `subsasgn' methods to optimize out |
681 redundant copies. For more information, see the manual. | |
9595 | 682 |
10453 | 683 ** More efficient matrix division handling. Octave is now able to |

688 V / M |
9664 | 689 |
10118 | 690 (M is a matrix and V is a vector) more efficiently in certain cases. |
691 In particular, if M is triangular, all three expressions will be | |
692 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
10453 | 693 flags. Previously, all three expressions required a physical |
10118 | 694 transpose of M. |
9664 | 695 |
10118 | 696 ** More efficient handling of certain mixed real-complex matrix |
697 operations. For instance, if RM is a real matrix and CM a complex | |
698 matrix, | |
9664 | 699 |
10118 | 700 RM * CM |
9664 | 701 |
702 can now be evaluated either as | |
703 | |
704 complex (RM * real (CM), RM * imag (CM)) | |
705 | |
706 or as | |
707 | |
708 complex (RM) * CM, | |
709 | |
10453 | 710 depending on the dimensions. The first form requires more |
711 temporaries and copying, but halves the FLOP count, which normally | |
712 brings better performance if RM has enough rows. Previously, the | |
713 second form was always used. | |
9664 | 714 |
11111 | 715 Matrix division is similarly affected. |
9664 | 716 |
10118 | 717 ** More efficient handling of triangular matrix factors returned from |
718 factorizations. The functions for computing QR, LU and Cholesky | |
719 factorizations will now automatically return the triangular matrix | |
720 factors with proper internal matrix_type set, so that it won't need | |
721 to be computed when the matrix is used for division. | |
9717 | 722 |
10118 | 723 ** The built-in `sum' function now handles the non-native summation |
724 (i.e., double precision sum of single or integer inputs) more | |
725 efficiently, avoiding a temporary conversion of the whole input | |
726 array to doubles. Further, `sum' can now accept an extra option | |
727 argument, using a compensated summation algorithm rather than a | |
728 straightforward sum, which significantly improves precision if lots | |
729 of cancellation occurs in the summation. | |
9717 | 730 |
10118 | 731 ** The built-in `bsxfun' function now uses optimized code for certain |
732 cases where built-in operator handles are passed in. Namely, the | |
733 optimizations concern the operators `plus', `minus', `times', | |
734 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
735 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
736 functions `min' and `max'. Optimizations only apply when both | |
737 operands are of the same built-in class. Mixed real/complex and | |
738 single/double operations will first convert both operands to a | |
739 common type. | |
9745 | 740 |
10118 | 741 ** The `strfind' and `strrep' functions now have compiled |
742 implementations, facilitating significantly more efficient searching | |
743 and replacing in strings, especially with longer patterns. The code | |
744 of `strcat' has been vectorized and is now much more efficient when | |
745 many strings are concatenated. The `strcmpi' and `strncmpi' | |
746 functions are now built-in functions, providing better performance. | |

10453 | 771 ** rem and mod are now built-in functions. They also handle integer |
772 types efficiently using integer arithmetic. | |
10437 | 773 |
10536 | 774 ** Sparse indexing and indexed assignment has been mostly rewritten. |
775 Since Octave uses compressed column storage for sparse matrices, | |
776 major attention is devoted to operations manipulating whole columns. | |
777 Such operations are now significantly faster, as well as some other | |
778 important cases. | |
779 | |
780 Further, it is now possible to pre-allocate a sparse matrix and | |
781 subsequently fill it by assignments, provided they meet certain | |
782 conditions. For more information, consult the `spalloc' function, | |
783 which is no longer a mere dummy. Consequently, nzmax and nnz are no | |
11111 | 784 longer always equal in Octave. Octave may also produce a matrix |
785 with nnz < nzmax as a result of other operations, so you should | |

786 consistently use nnz unless you really want to use nzmax (i.e., the |
11111 | 787 space allocated for nonzero elements). |
10536 | 788 |
789 Sparse concatenation is also affected, and concatenating sparse | |
790 matrices, especially larger collections, is now significantly more | |
11111 | 791 efficient. This applies to both the [] operator and the |
10536 | 792 cat/vertcat/horzcat functions. |
793 | |
11111 | 794 ** It is now possible to optionally employ the xGESDD LAPACK drivers |
14188 | 795 for computing the singular value decomposition using svd, instead |
11111 | 796 of the default xGESVD, using the configuration pseudo-variable |
797 svd_driver. The xGESDD driver can be up to 6x times faster when | |
798 singular vectors are requested, but is reported to be somewhat less | |
10639 | 799 robust on highly ill-conditioned matrices. |
800 | |

802 confirm_recursive_rmdir (or the above mentioned svd_driver), now | |

1046 on statements with dbstop should work correctly now. Stepping | |
1047 into and over functions, and stepping one statement at a time | |
1048 (with dbstep) now works. Moving up and down the call stack with | |
1049 dbup and dbdown now works. The dbstack function is now available | |
1050 to print the current function call stack. The new dbquit function | |
1051 is available to exit the debugging mode. | |
1052 | |
1053 ** Improved traceback error messages. | |
1054 | |
1055 Traceback error messages are much more concise and easier to | |
1056 understand. They now display information about the function call | |
1057 stack instead of the stack of all statements that were active at | |
1058 the point of the error. | |

1061 |
8737 | 1062 Octave now includes OOP features and the user can create their own |
1063 class objects and overloaded functions and operators. For | |
1064 example, all methods of a class called "myclass" will be found in | |
1065 a directory "@myclass" on the users path. The class specific | |
1066 versions of functions and operators take precedence over the | |
1067 generic versions of these functions. | |
1068 | |
1069 New functions related to OOP include | |
7189 | 1070 |
8737 | 1071 class inferiorto isobject loadobj methods superiorto |
1072 | |
1073 See the Octave manual for more details. | |
7038 | 1074 |
8747 | 1075 ** Parsing of Command-style Functions. |
1076 | |
1077 Octave now parses command-style functions without needing to first | |
1078 declare them with "mark_as_command". The rules for recognizing a | |
1079 command-style function calls are | |
1080 | |
1081 * A command must appear as the first word in a statement, | |
1082 followed by a space. | |
1083 | |
1084 * The first character after the space must not be '=' or '(' | |
1085 | |
1086 * The next token after the space must not look like a binary | |
1087 operator. | |
1088 | |
1089 These rules should be mostly compatible with the way Matlab parses | |
1090 command-style function calls and allow users to define commands in | |
1091 .m files without having to mark them as commands. | |
1092 | |
1093 Note that previous versions of Octave allowed expressions like | |
1094 | |
1095 x = load -text foo.dat | |
1096 | |
1097 but an expression like this will now generate a parse error. In | |
1098 order to assign the value returned by a function to a variable, | |
1099 you must use the normal function call syntax: | |
1100 | |
1101 x = load ("-text", "foo.dat"); | |
1102 | |
8737 | 1103 ** Block comments. |
1104 | |
8747 | 1105 Commented code can be between matching "#{" and "#}" or "%{" and |
1106 "%}" markers, even if the commented code spans several line. This | |
1107 allows blocks code to be commented, without needing to comment | |
1108 each line. For example, | |
5814 | 1109 |
8747 | 1110 function [s, t] = func (x, y) |
1111 s = 2 * x; | |
1112 #{ | |
1113 s *= y; | |
1114 t = y + x; | |
1115 #} | |

1171 conversions between cells, structs and cs-lists. This usually reduces |
8755 | 1172 both time and memory consumption. |
9128 | 1173 Also, Octave will now attempt to detect and optimize usage of a vector |
1174 as a stack, when elements are being repeatedly inserted at/removed from | |
1175 the end of the vector. | |
8755 | 1176 |
8738 | 1177 ** Improved performance for reduction operations. |
1178 | |
8755 | 1179 The performance of the sum, prod, sumsq, cumsum, cumprod, any, all, |

1184 The performance of sort has been improved, especially when sorting | |
10453 | 1185 indices are requested. An efficient built-in issorted |
1186 implementation was added. The sortrows function now uses a more | |

1196 subtracting a scalar, and multiplying by a scalar. Ranges with zero |
10453 | 1197 increment are allowed and can be constructed using the built-in |
1198 function `ones'. | |
9006 | 1199 |
1200 ** Various performance improvements. | |
1201 | |
10453 | 1202 Performance of a number of other built-in operations and functions |
1203 was improved, including: | |
9006 | 1204 |
1205 * logical operations | |
1206 * comparison operators | |
1207 * element-wise power | |
1208 * accumarray | |

1211 * isinf | |

1214 * repmat | |
1215 * strcmp | |
1216 | |
8737 | 1217 ** 64-bit integer arithmetic. |
1218 | |
1219 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
1220 supported, with saturation semantics like the other integer types. | |
1221 Performance of most integer arithmetic operations has been | |
1222 improved by using integer arithmetic directly. Previously, Octave | |
1223 performed integer math with saturation semantics by converting the | |
1224 operands to double precision, performing the operation, and then | |
1225 converting the result back to an integer value, truncating if | |
1226 necessary. | |
1227 | |
8885 | 1228 ** Diagonal and permutation matrices. |
1229 | |
1230 The interpreter can now treat diagonal and permutation matrices as | |
1231 special objects that store only the non-zero elements, rather than | |
1232 general full matrices. Therefore, it is now possible to construct | |
1233 and use these matrices in linear algebra without suffering a | |
1234 performance penalty due to storing large numbers of zero elements. | |
1235 | |
1236 ** Improvements to fsolve. | |
1237 | |
1238 The fsolve function now accepts an option structure argument (see | |
1239 also the optimset function). The INFO values returned from fsolve | |
1240 have changed to be compatible with Matlab's fsolve function. | |
1241 Additionally, fsolve is now able to solve overdetermined systems, | |
1242 complex-differentiable complex systems, systems with a sparse | |
1243 jacobian and can work in single precision if given single precision | |

1247 | |
1248 The norm function is now able to compute row or column norms of a | |
1249 matrix in a single call, as well as general matrix p-norms. | |
1250 | |
1251 ** New functions for computing some eigenvalues or singular values. | |
1252 | |
1253 The eigs and svds functions have been included in Octave. These | |
1254 functions require the ARPACK library (now distributed under a | |
1255 GPL-compatible license). | |
1256 | |
1257 ** New QR and Cholesky factorization updating functions. | |

8885 | 1298 ** Changes to strcat. |
1299 | |
1300 The strcat function is now compatible with Matlab's strcat | |
1301 function, which removes trailing whitespace when concatenating | |
1302 character strings. For example | |
1303 | |
1304 strcat ('foo ', 'bar') | |
1305 ==> 'foobar' | |
1306 | |
1307 The new function cstrcat provides the previous behavior of | |
1308 Octave's strcat. | |
1309 | |
1310 ** Improvements to the help functions. | |

1312 The help system has been mostly re-implemented in .m files to make |
8885 | 1313 it easier to modify. Performance of the lookfor function has been |
1314 greatly improved by caching the help text from all functions that | |
1315 are distributed with Octave. The pkg function has been modified | |
1316 to generate cache files for external packages when they are | |
1317 installed. | |
