Computes size of scratchpad memory required for hetrf (USM Version) function. This routine belongs to the mkl::lapack namespace.
template<typename T>
std::int64_t hetrf_scratchpad_size(cl::sycl::queue &queue, mkl::uplo uplo, std::int64_t n, std::int64_t lda);
Computes the number of elements of type T the scratchpad memory to be passed to the hetrf (buffer or USM version) function should be able to hold.
Device queue where calculations by the hetrf (buffer or USM version) function will be performed.
Indicates whether the upper or lower triangular part of A is stored and how A is factored:
If uplo = uplo::upper, the array a stores the upper triangular part of the matrix A, and A is factored as U*D*UH.
If uplo = uplo::lower, the array a stores the lower triangular part of the matrix A, and A is factored as L*D*LH.
The order of matrix A (0≤n).
The leading dimension of a.
