gerqf_scratchpad_size¶
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.
gerqf_scratchpad_size¶
Syntax
namespace oneapi::mkl::lapack {
template <typename T>
std::int64_t gerqf_scratchpad_size(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.
