 .
 BTF permutation to block triangular form (beta)
 .
 COLAMD column approximate minimum degree ordering
 .
 CCOLAMD constrained column approximate minimum degree ordering
 .
 CHOLMOD sparse Cholesky factorization
 .
 CSparse a concise sparse matrix package
 .
 CXSparse CSparse extended: complex matrix, int and long int support
 .
 KLU sparse LU factorization, primarily for circuit simulation
 .
 LDL a simple LDL' factorization
 .
 UMFPACK sparse LU factorization
 .
 UFconfig configuration file for all the above packages.
