csparse, a C code which carries out the direct solution of sparse linear systems, by Timothy Davis.
csparse_test01 reads an ST matrix from a file and performs basis matrix operations.
csparse_test02 reads an ST matrix from a file and solves a linear system.
csparse_test03 reads an ST matrix from a file, solves a linear system, and performs an update/downdate.
