oneapi::mkl::sparse::release_matmat_descr
Releases oneapi::mkl::sparse::matmat_descr_t object and sets it to NULL.
Description
The oneapi::mkl::sparse::release_matmat_descr routine releases the oneapi::mkl::sparse::matmat_descr_t object and sets it to NULL.
A common usage model for the matmat descriptor is the following
using namespace oneapi::mkl;
sparse::matmat_descr_t descr = nullptr;
sparse::init_matmat_descr(&descr);
// example descriptor for general
// C = A * B
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::nontrans;
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 release_matmat_descr ( oneapi::mkl::sparse::matmat_descr_t *p_descr );
}

Input Parameters
- p_descr
-
The address of an initialized matmat descriptor object (previously allocated in sparse::init_matmat_descr()) to be deallocated in this routine.
Output Parameters
- p_descr
-
On return, the address will be updated to point to a null sparse::matmat_descr_t; the matmat descriptor object that was previously pointed to, will have been deallocated.
