CC_IO
Read and Write Compressed Column (CC) Sparse Matrix Files


CC_IO, a C 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.
