oneapi::mkl::sparse::init_matmat_descr¶
Allocates and initializes a oneapi::mkl::sparse::matmat_descr_t object to default values.
Description¶
The oneapi::mkl::sparse::init_matmat_descr routine allocates and initializes the oneapi::mkl::sparse::matmat_descr_t object with default
values, otherwise it throws an exception.
Note
Refer to Exceptions for a detailed description of the exceptions thrown.
A common usage model for the matmat descriptor is the following
using namespace oneapi::mkl;
sparse::matmat_descr_t descr = NULL;
sparse::init_matmat_descr(descr);
// example descriptor for general
// C = A * B^T
sparse::matrix_view_descr viewA = sparse::matrix_view_descr::general;
sparse::matrix_view_descr viewB = sparse::matrix_view_descr::general;
sparse::matrix_view_descr viewC = sparse::matrix_view_descr::general;
transpose opA = transpose::nontrans;
transpose opB = transpose::trans;
sparse::set_matmat_data(descr, viewA, opA, viewB, opB, viewC);
// use descr in sparse::matmat() api
sparse::release_matmat_descr(descr);
API¶
Syntax¶
namespace oneapi::mkl::sparse {
void init_matmat_descr ( oneapi::mkl::sparse::matmat_descr_t *descr );
