crs_io, a Python code which reads and writes Compressed Row Storage (CRS) sparse matrix files.
An MxN sparse matrix of NZ nonzero entries in compressed row format is described by three items:
The nonzero entries of row I are stored in locations ROW(I) through ROW(I+1)-1 of COL and VAL.

crs_io is available in a MATLAB version and a MATLAB version.
ccs_io, a Python code which reads and writes sparse linear systems stored in the Compressed Column Storage (CCS) format.
crs, a dataset directory which contains examples of the Compressed Column Storage (CCS) sparse matrix file format;
ge_to_crs, a Python code which converts a matrix from General (GE) to Compressed Row Storage (CRS) format.
st_io, a Python code which reads and writes sparse linear systems stored in the Sparse Triplet (ST) format.
