Computes size of scratchpad memory required for potri (USM Version) function. This routine belongs to the mkl::lapack namespace.
template<typename T>
std::int64_t potri_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 potri (buffer or USM version) function should be able to hold.
Device queue where calculations by the potri (buffer or USM version) function will be performed.
Indicates how the input matrix A has been factored:
If uplo = mkl::uplo::upper, the upper triangle of A is stored.
If uplo = mkl::uplo::lower, the lower triangle of A is stored.
Specifies the order of the matrix A (0≤n).
The leading dimension of a.
