getri_batch_scratchpad_size (Strided Version)
Computes size of scratchpad memory required for getri_batch (Out-of-place, Strided 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 getri_batch (Out-of-place, Strided Version) function should be able to hold.
API
Syntax
namespace oneapi::mkl::lapack { std::int64_t getri_batch_scratchpad_size(sycl::queue &queue, std::int64_t n, std::int64_t lda, std::int64_t stride_a, std::int64_t stride_ipiv, std::int64_t ldainv, std::int64_t stride_ainv, std::int64_t batch_size) }
Input Parameters
- queue
-
Device queue where calculations will be performed.
- n
-
The order of the matrices Ai (n ≥ 0).
- lda
-
The leading dimension of Ai (lda ≥ max(1, n)).
- stride_a
-
The stride between the beginnings of matrices Ai inside the batch array a (stride_a ≥ max(1, lda * n)).
- stride_ipiv
-
The stride between the beginnings of arrays ipivi inside the array ipiv (stride_ipiv ≥ max(1, n)).
- ldainv
-
The leading dimension of Ainvi (ldainv ≥ max(1, n)).
- stride_ainv
-
The stride between the beginnings of matrices Ainvi inside the batch array ainv (stride_ainv ≥ max(1, ldainv * n)).
- batch_size
-
The number of problems in a batch (batch_size ≥ 0).
