Computes size of scratchpad memory required for hetrd (USM Version) function. This routine belongs to the mkl::lapack namespace.
template<typename T>
std::int64_t hetrd_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 hetrd (buffer or USM version) function should be able to hold.
Device queue where calculations by the hetrd (buffer or USM version) function will be performed.
Must be uplo::upper or uplo::lower.
If uplo = uplo::upper, a stores the upper triangular part of A.
If uplo = uplo::lower, a stores the lower triangular part of A.
The order of the matrices A(0≤n).
The leading dimension of a; at least max(1, n)
Exceptions
