| Summary: | 0000462: IMPLEMENTED: sparse matrix improvements | ||||
| Description: |
New sparse matrix functions * SparseGetRow() allows to read I-th row from CRS representation * SparseConvertToHash() allows to perform in-place conversion of the sparse matrix to Hash table storage format * SparseCopyToHash() and SparseCopyToCRS() allow to perform out-of-place conversion of the sparse matrix to another storage format * SparseGetType(), SparseIsHash(), SparseIsCRS() functions allow to determine sparse storage type Performance improvements: * SparseRewriteExisting() now has O(logN) performance for CRS matrices |
