suitesparse is a collection of libraries for computations involving sparse
matrices. The package includes the following libraries:
AMD approximate minimum degree ordering
BTF permutation to block triangular form
CAMD constrained approximate minimum degree ordering
COLAMD column approximate minimum degree ordering
CCOLAMD constrained column approximate minimum degree ordering
CHOLMOD sparse Cholesky factorization
CSparse a concise sparse matrix package
CXSparse int/long/real/complex version of CSparse
KLU sparse LU factorization, BLAS-free
LDL a simple LDL factorization
SQPR a multithread, multifrontal, rank-revealing sparse QR
factorization method
UMFPACK sparse LU factorization, with the BLAS
SuiteSparse_config configuration file for all the above packages.
RBio read/write files in Rutherford/Boeing format
