Computes size of scratchpad memory required for ungtr (USM Version) function. This routine belongs to the mkl::lapack namespace.
template<typename T>
std::int64_t ungtr_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 ungtr (buffer or USM version) function should be able to hold.
Device queue where calculations by the ungtr (buffer or USM version) function will be performed.
Must be uplo::upper or uplo::lower. Uses the same uplo as supplied to the hetrd (USM Version) function.
The order of matrix Q (0≤n).
The leading dimension of a (n≤lda).
