Summary

0000588: IMPLEMENTED: additional sparse matrix functions

Description

New sparse linear algebra functions:
* SparseTRMV - triangular matrix-vector multiply (CRS and SKS formats)
* SparseTRSV - triangular solver (CRS and SKS formats)
* SparseVSMV - triangular symmetric x'*A*x product (CRS and SKS formats)
* SparseTransposeSKS - in-place transposition of SKS matrix

New informational functions:
* SparseGetUpperCount() - counts symbolically non-zero strictly upper triangular elements in the matrix
* SparseGetLowerCount() - same for lower triangle

Improved functions:
* all sparse matrix-vector and matrix-matrix functions now support SKS format

Additional Information
