(buffer or USM version) function must be able to hold.
API¶
Syntax¶
namespace oneapi::mkl::lapack {
template<typename T>
orgtr_scratchpad_size(sycl::queue &queue,
mkl::uplo uplo,
std::int64_t n,
std::int64_t lda)
}
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
(lda ≥ n
).
