Sparse Matrix Storage Formats for Sparse BLAS Routines

The current version of
Intel® oneAPI Math Kernel Library
 Sparse BLAS Level 2 and Level 3 routines support the following point entry [Duff86] storage formats for sparse matrices:
  • compressed sparse row
     format (CSR) and its variations;
  • compressed sparse column
     format (CSC);
  • coordinate
     format;
  • diagonal
     format;
  • skyline
     storage format;
and one block entry storage format:
  • block sparse row
     format (BSR) and its variations.
For more information see "Sparse Matrix Storage Formats" in
the
Appendix
"Linear Solvers Basics"
.
Intel® oneAPI Math Kernel Library
 provides auxiliary routines -matrix converters - that convert sparse matrix from one storage format to another.
