Compressed Sparse Row or Column (CSR|CSC)

A sparse matrix or sparse array is a matrix in which most of the elements are zero.

Description

The compressed sparse row (CSR) represents a matrix M by three (one-dimensional) arrays, that respectively contain nonzero values, the extents of rows, and column indices.

CSC is similar to CSR except that values are read first by column, a row index is stored for each value, and column pointers are stored.

Purpose

This repo contents scripts that transform sparse array --> CSC|CSR, DSCC|DCSR and GraphToC2

How to use ?

Just run matrix_sparse.exe program

./matrix_sparse.exe
