Sparse Matrix Storage Formats for Sparse BLAS Routines

The current version of Intel MKL Sparse BLAS Level 2 and Level 3 routines support the following point entry [Duff86] storage formats for sparse matrices:

and one block entry storage format:

For more information see "Sparse Matrix Storage Formats" in the Appendix"Linear Solvers Basics".

Intel MKL provides auxiliary routines - matrix converters - that convert sparse matrix from one storage format to another.
