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(cl::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.
