Enums

cusparseAction_t

This type indicates whether the operation is performed only on indices or on data and indices.

cusparseColorAlg_t

cusparseCsr2CscAlg_t

cusparseDenseToSparseAlg_t

cusparseDiagType_t

This type indicates if the matrix diagonal entries are unity. The diagonal elements are always assumed to be present, but if cusparseDiagType_t::CUSPARSE_DIAG_TYPE_UNIT is passed to an API routine, then the routine assumes that all diagonal entries are unity and will not read or modify those entries. Note that in this case the routine assumes the diagonal entries are equal to one, regardless of what those entries are actually set to in memory.

cusparseDirection_t

This type indicates whether the elements of a dense matrix should be parsed by rows or by columns (assuming column-major storage in memory of the dense matrix) in function cusparse[S|D|C|Z]nnz. Besides storage format of blocks in BSR format is also controlled by this type.

cusparseFillMode_t

This type indicates if the lower or upper part of a matrix is stored in sparse storage.

cusparseFormat_t

This type indicates the format of the sparse matrix. See cuSPARSE Storage Formats for their description.

cusparseIndexBase_t

This type indicates if the base of the matrix indices is zero or one.

cusparseIndexType_t

This type indicates the index type for representing the sparse matrix indices.

cusparseMatrixType_t

This type indicates the type of matrix stored in sparse storage. Notice that for symmetric, Hermitian and triangular matrices only their lower or upper part is assumed to be stored.

cusparseOperation_t

This type indicates which operations is applied to the related input (e.g. sparse matrix, or vector).

cusparseOrder_t

This type indicates the memory layout of a dense matrix.

cusparsePointerMode_t

This type indicates whether the scalar values are passed by reference on the host or device. It is important to point out that if several scalar values are passed by reference in the function call, all of them will conform to the same single pointer mode. The pointer mode can be set and retrieved using cusparseSetPointerMode and cusparseGetPointerMode routines, respectively.

cusparseSDDMMAlg_t
