Summary

0000410: IMPLEMENTED: sparse matrices

Description

Sparse matrix structure which supports:
* improved CRS format (for memory efficient operations) and Hash-Table representation (easy to use format, intended to simplify matrix creation)
* basic operations with elements: Set, Get, Add
* linear matrix-vector operations: A*x, A'*x, simultaneous calculation of both products
* linear matrix-matrix operations
* operations with symmetric matrices given by lower or upper triangle only

Steps To Reproduce
