CC_IO is a MATLAB library which reads and writes compressed column (CC) sparse matrix files.
An MxN sparse matrix of NCC nonzero entries in compressed column format is described by three items:
The nonzero entries of column J are stored in locations CCC(J) through CCC(J+1)-1 of ICC and ACC.

CC_IO is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version.
CC, a data directory which contains examples of the Compressed Column (CC) sparse matrix file format;
CC_TO_ST, a MATLAB library which converts a sparse matrix from compressed column (CC) to sparse triple (ST) format.
HB_IO, a MATLAB library which reads and writes sparse linear systems stored in the Harwell Boeing (HB) format for sparse matrices.
MM_IO, a MATLAB library which reads and writes sparse linear systems stored in the Matrix Market (MM) format.
ST_IO, a MATLAB library which reads and writes sparse linear systems stored in the Sparse Triplet (ST) format.
ST_TO_CC, a MATLAB library which converts sparse matrix data from Sparse Triplet (ST) format to Compressed Column (CC) format.
