SuiteSparse: A Suite of Sparse matrix packages
------------------
SuiteSparse/README
------------------
================================================================================
QUICK START FOR MATLAB USERS: unzip the SuiteSparse.zip file, then in the
MATLAB Command Window, cd to the SuiteSparse directory and type
SuiteSparse_install. All packages will be compiled, and several demos will be
run.
================================================================================
Nov 1, 2007. SuiteSparse version 3.1
AMD approximate minimum degree ordering
CAMD constrained approximate minimum degree ordering
COLAMD column approximate minimum degree ordering
CCOLAMD constrained column approximate minimum degree ordering
BTF permutation to block triangular form
KLU sparse LU factorization, primarily for circuit simulation.
Requires AMD, COLAMD, and BTF. Optionally uses CHOLMOD,
CAMD, CCOLAMD, and METIS.
UMFPACK sparse LU factorization. Requires AMD and the BLAS.
CHOLMOD sparse Cholesky factorization. Requires AMD, COLAMD, CCOLAMD,
the BLAS, and LAPACK. Optionally uses METIS.
UFconfig configuration file for all the above packages. The
UFconfig/UFconfig.mk is included in the Makefile's of all
packages. CSparse and RBio do not use UFconfig.
CSparse a concise sparse matrix package, developed for my upcoming
book, "Direct Methods for Sparse Linear Systems", to be
published by SIAM.
CXSparse CSparse Extended. Includes support for complex matrices
and both int or long integers.
RBio read/write sparse matrices in Rutherford/Boeing format
UFcollection toolbox for managing the UF Sparse Matrix Collection
LPDASA LP dual active set algorithm (to appear)
MESHND 2D and 3D mesh generation and nested dissection ordering
SSMULT sparse matrix multiply for MATLAB
LINFACTOR simple m-file demonstrating how to use LU and CHOL in
MATLAB to solve Ax=b
MATLAB_Tools various simple m-files for use in MATLAB
CHOLMOD optionally uses METIS 4.0.1
(http://www-users.cs.umn.edu/~karypis/metis). To use METIS, place a copy of
the metis-4.0 directory in the same directory (CHOLMOD_ACM_TOMS) containing
this README file. The use of METIS will improve the ordering quality in
CHOLMOD.
Refer to each package for license, copyright, and author information. All
codes are authored or co-authored by Timothy A. Davis, CISE Dept., Univ. of
Florida. email: my last name @ cise dot ufl dot edu.

If you use SuiteSparse_install in MATLAB, stop reading here.
================================================================================
----------------------------
To use "make" in Unix/Linux:
----------------------------
(1) Use the right BLAS and LAPACK libraries
See http://www.netlib.org/blas for the Fortran reference BLAS (slow, but
they work). See http://www.tacc.utexas.edu/~kgoto/ or
http://www.cs.utexas.edu/users/flame/goto/ for an optimized BLAS. See
http://www.netlib.org/lapack for LAPACK. The UFconfig/UFconfig.mk file
assumes the vanilla BLAS (-lblas). You should use an optimized BLAS;
otherwise UMFPACK and CHOLMOD will be slow. Change -lblas to -l(your BLAS
library here) in the UFconfig/UFconfig.mk file.
(2) Configure METIS (or don't use METIS)
cd to metis-4.0 and edit the Makefile.in file. I recommend making these
changes to metis-4.0/Makefile.in:
CC = gcc
OPTFLAGS = -O3
COPTIONS = -fexceptions -D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE
Next, cd to metis-4.0 and type "make".
If you do not wish to use METIS, then edit the UFconfig/UFconfig.mk file,
and change the line
CHOLMOD_CONFIG =
to
CHOLMOD_CONFIG = -DNPARTITION
Also change the line
METIS = ../../metis-4.0/libmetis.a
to
METIS =
(3) Make other changes to UFconfig/UFconfig.mk as needed
Edit the UFconfig/UFconfig.mk file as needed. Directions are in that file.
If you have compiled SuiteSparse already (partially or completely), then
whenever you edit the UFconfig/UFconfig.mk file, you should then type
"make purge" (or "make realclean") in this directory.
(4) Type "make" in this directory. All packages will be be compiled. METIS
will be compiled if you have it. Several demos will be run.
The libraries will appear in */Lib/*.a. Include files, as needed by user
programs that use CHOLMOD, AMD, CAMD, COLAMD, CCOLAMD, BTF, KLU, UMFPACK,
LDL, etc. are in */Include/*.h.
The METIS library is in metis-4.0/libmetis.a. METIS Include files (not
needed by the end user of SuiteSparse) are in located in metis-4.0/Lib/*.h.
