Computes size of scratchpad memory required for getrs (USM Version) function. This routine belongs to the mkl::lapack namespace.
template<typename T>
std::int64_t getrs_scratchpad_size(cl::sycl::queue &queue, mkl::transpose trans, std::int64_t n, std::int64_t nrhs, std::int64_t lda, std::int64_t ldb);
Computes the number of elements of type T the scratchpad memory to be passed to the getrs (buffer or USM version) function should be able to hold.
Device queue where calculations by the getrs (buffer or USM version) function will be performed.
Indicates the form of the equations:
If trans=mkl::transpose::nontrans, then A*X = B is solved for X.
If trans=mkl::transpose::trans, then AT*X = B is solved for X.
If trans=mkl::transpose::conjtrans, then AH*X = B is solved for X.
The order of the matrix A and the number of rows in matrix B(0≤n).
The number of right-hand sides (0≤nrhs).
The leading dimension of a.
The leading dimension of b.
