UMFPACK Interface (sparse)

  • PlotSparseplot the pattern of non nul elements of a sparse matrix
  • ReadHBSparseread a Harwell-Boeing sparse format file
  • cond2spcomputes an approximation of the 2-norm condition number of a s.p.d. sparse matrix
  • condestspestimate the condition number of a sparse matrix
