sparsekit, a Fortran77 code which carries out a number of operations on sparse matrices, particularly conversion between various sparse formats.
Sample problem 4 takes a banded matrix of order 16, stored as a dense matrix, converts it to CSR format and sorted CSR format.
Sample problem 8 generates three sample matrices from the Zlatev set, and writes them to Harwell-Boeing format files:
Sample problem 14 generates a sample CSR matrix and converts it to an NCF (nonsymmetric coordinate format) used by NSPCG.
