% CXSparse       extended version of CSparse (32-bit/64-bit/real/complex)
% ssget          interface to SuiteSparse Matrix Collection
% KLU            sparse LU factorization (left-looking)

% FACTORIZE      an object-oriented solver for x=A\b
% SPARSEINV      sparse inverse subset; computes entries of inv(sparse(A))
% MATLAB_Tools   various simple m-files and demos
% SuiteSparseQR  sparse QR factorization
% spqr_rank      MATLAB toolbox for sparse rank deficient matrices
%
% Example:
%    SuiteSparse_install        % compile and prompt to run each package's demo
%    SuiteSparse_install(0)     % compile but do not run the demo
%    SuiteSparse_install(1)     % compile and run the demos with no prompts
%    help SuiteSparse           % for more details
%
% See also AMD, COLAMD, CAMD, CCOLAMD, CHOLMOD, UMFPACK, CSPARSE, CXSPARSE,
%      ssget, RBio, SuiteSparseCollection, KLU, BTF, MESHND, SSMULT, LINFACTOR,
%      SPOK, SPQR_RANK, SuiteSparse, SPQR, PATHTOOL, PATH, FACTORIZE,
%      SPARSEINV, Mongoose, GraphBLAS, SPEX.
%
% This script installs the full-featured CXSparse rather than CSparse.
%
% If you get errors building or using METIS, just remove the
% CHOLMOD/SuiteSparse_metis folder.  This often occurs on Windows.
%
% Before using SuiteSparse_install, you must compile the GraphBLAS library for
% use in MATLAB.  In the system shell while in the SuiteSparse folder, type
% "make gbmatlab".  You must then either install the libgraphblas_matlab.so
% library system-wide ( cd GraphBLAS/GraphBLAS ; make ; sudo make install), or
% install % your own copy ( make local ; make install ) and then add the
% SuiteSparse/lib folder to your LD_LIBRARY_PATH.  Restart MATLAB after
% compiling libgraphblas_matlab.so.
