sytrd_scratchpad_size#
Computes size of scratchpad memory required for sytrd function.
Description
sytrd_scratchpad_size
supports the following precisions.
T
float
double
Computes the number of elements of type T
the scratchpad memory to be passed to sytrd function should be able to hold.
Calls to this routine must specify the template parameter explicitly.
sytrd_scratchpad_size#
Syntax
namespace oneapi::mkl::lapack {
template <typename T>
std::int64_t sytrd_scratchpad_size(sycl::queue &queue, oneapi::mkl::uplo upper_lower, std::int64_t n, std::int64_t lda)
}
Input Parameters
- queue
Device queue where calculations by sytrd function will be performed.
- upper_lower
Must be
uplo::upper
oruplo::lower
.If
upper_lower = uplo::upper
, a stores the upper triangular part of \(A\).If
upper_lower = uplo::lower
, a stores the lower triangular part of \(A\).- n
The order of the matrices \(A\) \((0 \le n)\).
- lda
The leading dimension of
a
.
Return Value
The number of elements of type T
the scratchpad memory to be passed to sytrd function should be able to hold.
