LDL is a set of concise routines for factorizing symmetric positive-
definite sparse matrices, with some applicability to symmetric
indefinite matrices. Its primary purpose is to illustrate much of the
basic theory of sparse matrix algorithms in as concise a code as
possible, including an elegant new method of sparse symmetric
factorization that computes the factorization row-by-row but stores
it column-by-column. The entire symbolic and numeric factorization
consists of a total of only 49 lines of code. The package is written
in C, and includes a MATLAB interface.
LDL 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.
