SuiteSparse is a set of sparse matrices libraries.
It contains:
  * AMD: symmetric approximate minimum degree
  * BTF: permutation to block triangular form (beta)
  * CCOLAMD: constrained column approximate minimum degree
  * COLAMD: column approximate minimum degree
  * CHOLMOD: sparse supernodal Cholesky factorization and
    update/downdate
  * KLU: sparse LU factorization, for circuit simulation (beta)
  * LDL: a simple LDL^T factorization
  * UMFPACK: sparse multifrontal LU factorization
  * UFconfig: common configuration for all of the above
  * CSparse: a concise sparse matrix package
  * CXSparse: and extended version of CSparse
