getri_scratchpad_size¶
Computes size of scratchpad memory required for getri function.
Description
getri_scratchpad_size supports the following precisions.
T
float
double
std::complex<float>
std::complex<double>
Computes the number of elements of type T the scratchpad memory to be passed to getri function should be able to hold.
Calls to this routine must specify the template parameter
explicitly.
getri_scratchpad_size¶
Syntax
namespace oneapi::mkl::lapack {
template <typename T>
std::int64_t getri_scratchpad_size(sycl::queue &queue, std::int64_t n, std::int64_t lda)
}
Input Parameters
- queue
Device queue where calculations by getri function will be performed.
- n
The order of the matrix \(A\) \((0 \le n)\).
- lda
The leading dimension of
a\((n \le \text{lda})\).
Return Value
The number of elements of type T the scratchpad memory to be passed to getri function should be able to hold.
