st_to_ccs is available in a C version and a C++ version and a Fortran90 version and a MATLAB version and an Octave version and a Python version.
ccs, a data directory which contains examples of the Compressed Column Storage (CCS) sparse matrix file format;
ccs_io, a C code which reads and writes sparse linear systems stored in the Compressed Column Storage (CCS) format.
ccs_to_st, a C code which converts a sparse matrix from Compressed Column Storage (CCS) to sparse triple (ST) format.
st, a data directory which contains examples of the Sparse Triplet (ST) format, a sparse matrix file format, storing just (I,J,A(I,J)), and using zero-based indexing.
st_io, a C code which reads and writes sparse linear systems stored in the ST "sparse triplet" Sparse Matrix format.
wathen_matrix, a C code which compares storage schemes (full, banded, sparse triplet) and solution strategies (Linpack full, Linpack banded, conjugate gradient (CG)) for linear systems involving the Wathen matrix, which can arise when solving a problem using the finite element method (FEM).
