May 31, 2007: version 2.7.0
|
|
|
|
* ported to 64-bit MATLAB
|
|
|
|
* subdirectories added (Source/, Include/, Lib/, Doc/, MATLAB/, Demo/)
|
|
|
|
Dec 12, 2006, version 2.5.2
|
|
|
|
* minor MATLAB cleanup. MATLAB functions renamed colamd2 and symamd2,
|
|
so that they do not conflict with the built-in versions. Note that
|
|
the MATLAB built-in functions colamd and symamd are identical to
|
|
the colamd and symamd functions here.
|
|
|
|
Aug 31, 2006: Version 2.5.1
|
|
|
|
* minor change to colamd.m and symamd.m, to use etree instead
|
|
of sparsfun.
|
|
|
|
Apr. 30, 2006: Version 2.5
|
|
|
|
* colamd_recommended modified, to do more careful integer overflow
|
|
checking. It now returns size_t, not int. colamd_l_recommended
|
|
also returns size_t. A zero is returned if an error occurs. A
|
|
postive return value denotes success. In v2.4 and earlier,
|
|
-1 was returned on error (an int or long).
|
|
|
|
* long replaced with UF_long integer, which is long except on WIN64.
|
|
|
|
Nov 15, 2005:
|
|
|
|
* minor editting of comments; version number (2.4) unchanged.
|
|
|
|
Changes from Version 2.3 to 2.4 (Aug 30, 2005)
|
|
|
|
* Makefile now relies on ../UFconfig/UFconfig.mk
|
|
|
|
* changed the dense row/col detection. The meaning of the knobs
|
|
has thus changed.
|
|
|
|
* added an option to turn off aggressive absorption. It was
|
|
always on in versions 2.3 and earlier.
|
|
|
|
* added a #define'd version number
|
|
|
|
* added a function pointer (colamd_printf) for COLAMD's printing.
|
|
|
|
* added a -DNPRINT option, to turn off printing at compile-time.
|
|
|
|
* added a check for integer overflow in colamd_recommended
|
|
|
|
* minor changes to allow for more simpler 100% test coverage
|
|
|
|
* bug fix. If symamd v2.3 fails to allocate its copy of the input
|
|
matrix, then it erroneously frees a calloc'd workspace twice.
|
|
This bug has no effect on the MATLAB symamd mexFunction, since
|
|
mxCalloc terminates the mexFunction if it fails to allocate
|
|
memory. Similarly, UMFPACK is not affected because it does not
|
|
use symamd. The bug has no effect on the colamd ordering
|
|
routine in v2.3.
|
|
|
|
Changes from Version 2.2 to 2.3 (Sept. 8, 2003)
|
|
|
|
* removed the call to the MATLAB spparms ('spumoni') function.
|
|
This can take a lot of time if you are ordering many small
|
|
matrices. Only affects the MATLAB interface (colamdmex.c,
|
|
symamdmex.c, colamdtestmex.c, and symamdtestmex.c). The
|
|
usage of the optional 2nd argument to the colamd and symamd
|
|
mexFunctions was changed accordingly.
|
|
|
|
Changes from Version 2.1 to 2.2 (Sept. 23, 2002)
|
|
|
|
* extensive testing routines added (colamd_test.m, colamdtestmex.c,
|
|
and symamdtestmex.c), and the Makefile modified accordingly.
|
|
|
|
* a few typos in the comments corrected
|
|
|
|
* use of the MATLAB "flops" command removed from colamd_demo, and an
|
|
m-file routine luflops.m added.
|
|
|
|
* an explicit typecast from unsigned to int added, for COLAMD_C and
|
|
COLAMD_R in colamd.h.
|
|
|
|
* #include <stdio.h> added to colamd_example.c
|
|
|
|
|
|
Changes from Version 2.0 to 2.1 (May 4, 2001)
|
|
|
|
* TRUE and FALSE are predefined on some systems, so they are defined
|
|
here only if not already defined.
|
|
|
|
* web site changed
|
|
|
|
* UNIX Makefile modified, to handle the case if "." is not in your path.
|
|
|
|
|
|
Changes from Version 1.0 to 2.0 (January 31, 2000)
|
|
|
|
No bugs were found in version 1.1. These changes merely add new
|
|
functionality.
|
|
|
|
* added the COLAMD_RECOMMENDED (nnz, n_row, n_col) macro.
|
|
|
|
* moved the output statistics, from A, to a separate output argument.
|
|
The arguments changed for the C-callable routines.
|
|
|
|
* added colamd_report and symamd_report.
|
|
|
|
* added a C-callable symamd routine. Formerly, symamd was only
|
|
available as a mexFunction from MATLAB.
|
|
|
|
* added error-checking to symamd. Formerly, it assumed its input
|
|
was error-free.
|
|
|
|
* added the optional stats and knobs arguments to the symamd mexFunction
|
|
|
|
* deleted colamd_help. A help message is still available from
|
|
"help colamd" and "help symamd" in MATLAB.
|
|
|
|
* deleted colamdtree.m and symamdtree.m. Now, colamd.m and symamd.m
|
|
also do the elimination tree post-ordering. The Version 1.1
|
|
colamd and symamd mexFunctions, which do not do the post-
|
|
ordering, are now visible as colamdmex and symamdmex from
|
|
MATLAB. Essentialy, the post-ordering is now the default
|
|
behavior of colamd.m and symamd.m, to match the behavior of
|
|
colmmd and symmmd. The post-ordering is only available in the
|
|
MATLAB interface, not the C-callable interface.
|
|
|
|
* made a slight change to the dense row/column detection in symamd,
|
|
to match the stated specifications.
