ormqr_scratchpad_size
Computes size of scratchpad memory required for ormqr (USM Version) function. This routine belongs to the oneapi::mkl::lapack namespace.
Description
Computes the number of elements of type T the scratchpad memory to be passed to the ormqr (buffer or USM version) function must be able to hold.
API
Syntax
namespace oneapi::mkl::lapack { template<typename T> std::int64_t ormqr_scratchpad_size(sycl::queue &queue, mkl::side side, mkl::transpose trans, std::int64_t m, std::int64_t n, std::int64_t k, std::int64_t lda, std::int64_t ldc) }
Input Parameters
- queue
-
Device queue where calculations by the ormqr (buffer or USM version) function will be performed.
- side
-
If side=mkl::side::left, Q or QT is applied to C from the left.
If side=mkl::side::right, Q or QT is applied to C from the right.
- trans
-
If trans=mkl::transpose::trans, the routine multiplies C by Q.
If trans=mkl::transpose::nontrans, the routine multiplies C by QT.
- m
-
The number of rows in the matrix A (0 ≤ m).
- n
-
The number of columns in the matrix A (0 ≤ n ≤ m).
- k
-
The number of elementary reflectors whose product defines the matrix Q (0 ≤ k ≤ n).
- lda
-
The leading dimension of a.
- ldc
-
The leading dimension of c.

Return Values
The number of elements of type T the scratchpad memory to be passed to the ormqr (buffer or USM version) function must be able to hold.
