orgtr_scratchpad_size(cl::sycl::queue &queue, mkl::uplo uplo, std::int64_t n, std::int64_t lda)¶
Description
Computes the number of elements of type T the scratchpad memory to be passed to the orgtr (buffer or USM version) function should be able to hold.
Input Parameters
- queue
Device queue where calculations by the orgtr (buffer or USM version) function will be performed.
- uplo
Must be uplo::upper or uplo::lower. Uses the same uplo as supplied to the sytrd (USM Version) function.
- n
The order of matrix
Q(0≤n).- lda
The leading dimension of
a(n≤lda).
Exceptions
