mm_io is available in a C version and a Fortran90 version and a MATLAB version and an Octave version.
cc_io, a Fortran77 library which reads and writes sparse linear systems stored in the Compressed Column (CC) format.
dlap_io, a Fortran77 library which reads and writes files describing sparse matrices used by DLAP.
hb_read, a Fortran77 library which reads files in the Harwell Boeing (HB) sparse matrix format; This is a simplified interface intended to handle only the most common format, complex unsymmetric assembled (CUA) or real unsymmetric assembled (RUA).
MM, a data directory which contains a description and examples of the Matrix Market format for storing matrices.
SPARSE_DISPLAY, a Fortran77 library which can read information defining a matrix of numbers and display the sparsity pattern or location of the nonzero elements using gnuplot. This operation is already available in the built-in MATLAB "spy" command.
ST_IO, a Fortran77 library which reads and writes sparse linear systems stored in the Sparse Triplet (ST) format.
TEST_MAT, a Fortran77 library which defines various test matrices.
