Computes size of scratchpad memory required for gerqf function.

Description

gerqf_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 gerqf function should be able to hold. Calls to this routine must specify the template parameter explicitly.

Syntax

namespace oneapi::mkl::lapack {
template <typename T>
std::int64_t gerqf_scratchpad_size(cl::sycl::queue &queue, std::int64_t m, std::int64_t n, std::int64_t lda)
}


Input Parameters

queue

Device queue where calculations by the gerqf (buffer or USM version) function will be performed.

m

The number of rows in the matrix $$A$$ ($$0 \le m$$).

n

The number of columns in the matrix $$A$$ ($$0 \le n$$).

lda

The leading dimension of a; at least $$\max(1,m)$$.

Return Value

The number of elements of type T the scratchpad memory to be passed to gerqf function should be able to hold.
