Summary: Supernodal Sparse Cholesky Factorization and Update/Downdate
CHOLMOD is a set of ANSI C routines for sparse Cholesky factorization
and update/downdate. A MATLAB interface is provided.

The performance of CHOLMOD was compared with 10 other codes in a
paper by Nick Gould, Yifan Hu, and Jennifer Scott. see also their raw
data. Comparing BCSLIB-EXT, CHOLMOD, MA57, MUMPS, Oblio, PARDISO,
SPOOLES, SPRSBLKLLT, TAUCS, UMFPACK, and WSMP, on 87 large symmetric
positive definite matrices, they found CHOLMOD to be fastest for 42
of the 87 matrices. Its run time is either fastest or within 10% of
the fastest for 73 out of 87 matrices. Considering just the larger
matrices, it is either the fastest or within 10% of the fastest for
40 out of 42 matrices. It uses the least amount of memory (or within
10% of the least) for 35 of the 42 larger matrices. Jennifer Scott
and Yifan Hu also discuss the design considerations for a sparse
direct code.

CHOLMOD is part of the SuiteSparse sparse matrix suite.

* Wed Apr 26 2023 David Anes <>

* Sun Sep 04 2022 Christoph G <>
  - update to 5.13.0
    * GraphBLAS v7.2.0:  see GraphBLAS/Doc/ChangeLog for details.
    - performance:  more compact serialization (ZSTD added, now the
      default compression method).
    - MATLAB interface: faster linear indexing, reshape, bandwidth,
      istril, istriu, isbanded, isdiag.  C(I,J)=A can now grow the
      size of C.
    - features: reshape methods, cube root operator, isStoredElement
    - bugs: a minor bug; user-defined types were incorrectly limited to
      128 bytes in size in v7.0.3.
  - remove unused rules from rpmlintrc
* Wed Apr 13 2022 David Anes <>
  - update to 5.12.0:
    * GraphBLAS v7.0.3:  see GraphBLAS/Doc/ChangeLog for details.
    - performance: GrB_mxm, GrB_assign, and transpose
    - bug fix: vector iterator for bitmap
    - revised ACM TOMS submission: Doc/toms_parallel_grb2.pdf
    - spec bug: GrB_Matrix_diag was implemented incorrectly,
      thus requiring a version v7.x
* Tue Mar 15 2022 David Anes <>
  - Fix bundled library versions:
    * libmongoose: 2.0.3 -> 2.0.4
    * libspqr: 2.0.9 -> 2.1.0
    * libumfpack: 5.7.8 -> 5.7.9
  - Update to 5.11.0:
    * GraphBLAS v6.2.5: see GraphBLAS/Doc/ChangeLog for changes.
      Primary ones highlighted here:
    - v2.0 API: v6.x complies with the v2.0 C API of the GraphBLAS Spec.
      Note that GrB_wait, GrB_Info are now different than in the v1.3
      C API Specification (and in v5.x of SuiteSparse:GraphBLAS).
    - GxB_Iterator: to iterate over rows/cols/entries of a matrix or vector
    - GxB_eWiseUnion: like eWiseAdd but with the op always applied
    - GxB_Matrix/Vector_sort: to sort the vectors of a matrix
    - better performance: for sparse-times-dense and dense-times-sparse,
      in particular; also other cases for GrB_mxm, up to 10x faster.
    - Apple Silicon: port @GrB to Octave 7 (thanks to Gabor Szarnyas)
    - added cpu_features: by Google
    - added LZ4/LZ4HC: compression library, (BSD 2),
      v1.9.3, Copyright (c) 2011-2016, Yann Collet, All Rights Reserved.
    - iso-valued matrices and vectors: to exploit the common case of
      an unweighted graph
    - bug fixes: 4 bugs fixed since SuiteSparse 5.10.1 with
      GraphBLAS v5.0.5.  12 other bugs appeared in the interim but
      appeared in versions after v5.0.5 but fixed before ever
      affecting SuiteSparse itself.

    * GraphBLAS upgraded from v3.3 to v4.0.3 with many new features,
      and increased performance. Betweeness Centrality about 2x
      faster, and now faster than the GAP benchmark for larger
      matrices. BFS about 5x faster.

      the GNU GMP and MPRF libraries.
    * GraphBLAS v3.3.1: see the GraphBLAS/Doc/Changlog
    * replaced UFget with ssget: affects nearly all packages:
      UMFPACK, KLU, CHOLMOD, CXSparse/CSparse, etc,
      but their version numbers are left unchanged since it affects
      the MATLAB tests only, not the compiled libraries.
