UMFPACK Interface (sparse)
- PlotSparse plot the pattern of non nul elements of a sparse
matrix
- ReadHBSparse read a Harwell-Boeing sparse format file
- cond2sp computes an approximation of the 2-norm condition number
of a s.p.d. sparse matrix
- condestsp estimate the condition number of a sparse matrix
- rafiter (obsolete) iterative refinement for a s.p.d. linear
system
- res_with_prec computes the residual r = Ax-b with precision

- taucs_chsolve solve a linear sparse (s.p.d.) system given the
Cholesky factors
