 .
 CCOLAMD constrained column approximate minimum degree ordering
 .
 CHOLMOD sparse Cholesky factorization
 .
 CXSparse a concise sparse matrix package
 .
 KLU sparse LU factorization, primarily for circuit simulation
 .
 LDL a simple LDL' factorization
 .
 UMFPACK sparse LU factorization
 .
 RBio read/write sparse matrices in Rutherford/Boeing format
 .
 SPQR sparse QR factorization
 .
 GraphBLAS graph algorithms via sparse matrix operations on semirings
 .
 Mongoose graph partitioning library that can quickly compute edge cuts
 .
 SLIP_LU solves sparse linear systems in exact arithmetic
 .
 SuiteSparse_config configuration routines for all the above packages.
