The COLAMD column approximate minimum degree ordering algorithm
computes a permutation vector P such that the LU factorization of
A (:,P) tends to be sparser than that of A. The Cholesky
factorization of (A (:,P))'*(A (:,P)) will also tend to be sparser
than that of A'*A. SYMAMD is a symmetric minimum degree ordering
method based on COLAMD, available as a MATLAB-callable function. It
constructs a matrix M such that M'*M has the same pattern as A, and
then uses COLAMD to compute a column ordering of M. Colamd and symamd
tend to be faster and generate better orderings than their MATLAB
counterparts, colmmd and symmmd.
COLAMD is part of the SuiteSparse sparse matrix suite.

2019-04-06 - Jan Engelhardt <>
- Trim future visions from descriptions.
2019-04-02 - Christoph G <>
- Update to SuiteSparse 5.4.0
* GraphBLAS 2.2.2: many upgrades and new features, a few bug fixes
- Update to SuiteSparse 5.3.0
* new package: Mongoose (version 2.0.2)
- doc packages for AMD, CAMD, KLU, LDL, and Mongoose.
2019-03-20 - Stefan BrĂ¼ns <>
- Remove openmpi BuildRequires, all SuiteSparse libraries are MPI
2018-06-27 -
- Fix conditional to select the right gcc-c++ package, also for the
devel subpackge
2018-02-26 -
- Update to SuiteSparse 5.2.0
* GraphBLAS 2.0.1: bug fix to GxB_kron
* SuiteSparse_config: corrected back to SO_VERSION 5
* GraphBLAS 2.0.0: with changes to API to conform to the latest
specification.  The SO_VERSION of GraphBLAS must change,
as a result, since this affects both the ABI and API interface.
* CHOLMOD 3.1.12: bug fix (no change to the CHOLMOD ABI or API)
* KLU 1.3.9: minor edit, not a bug fix, but code is more clear now
- Update to SuiteSparse 5.1.2
* improved build process for GraphBLAS
* minor change to CSparse/Lib/Makefile, no change in CSparse version
- Update to SuiteSparse 5.1.1
* GraphBLAS added to top-level SuiteSparse/Makefile
* GraphBLAS 1.1.1: bug fix to *assign, split AxB for faster compile,
added memory usage statistics, AxB performance improvment
* minor update to [AMD CAMD KLU]/Doc/Makefile's, no change to
version numbers of AMD, CAMD, or KLU
- Update to SuiteSparse 5.1.0
* GraphBLAS 1.1.0
* minor update to SPQR Makefile (version remains unchanged;
no change to source)
- Update to SuiteSparse 5.0.0
* added GraphBLAS Version 1.0.0
* replaced UFget with ssget
- Use build-in build system instead of manually building everything
- Simplify spec file
- Add build_csparse_shared.patch to build CSparse as a shared library
2018-02-14 -
- Make openblas optional, using lapack instead
2017-10-16 -
- Fix csparselib define: libcsparse-%{csparseso}. This results in
the (wrongly named) package libcsparsever-3_1_9 being renamed to
libcsparse-3_1_9, matching the content of the package. The old
name is, exceptionally, obsoleted by the new package name (not
provided, as nothing but the -devel package should ever have
referenced the package by name). The obsolete is guarded to no
longer apply, should the version change.
2017-07-10 -
- Fix RPM groups.
- Trim pointless trailing line whitespace from descriptions.
% must be encoded as %%.
- Trim past-time history from suistesparse_config description.
