Computes size of scratchpad memory required for heevd (USM Version) function. This routine belongs to the mkl::lapack namespace.
template<typename T>
std::int64_t heevd_scratchpad_size(cl::sycl::queue &queue, mkl::job jobz, 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 heevd (buffer or USM version) function should be able to hold.
Device queue where calculations by the heevd (buffer or USM version) function will be performed.
Must be job::novec or job::vec.
If jobz = job::novec, then only eigenvalues are computed.
If jobz = job::vec, then eigenvalues and eigenvectors are computed.
Must be uplo::upper or uplo::lower.
If uplo = job::upper, a stores the upper triangular part of A.
If uplo = job::lower, a stores the lower triangular part of A.
The order of the matrix A (0≤n).
The leading dimension of a. Must be at least max(1,n).
Exceptions
