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.

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 arraya(stride_a≥max(1, lda * n)).- stride_ipiv
The stride between the beginnings of arrays
ipivi inside the arrayipiv(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 arrayainv(stride_ainv≥max(1, ldainv * n)).- batch_size
The number of problems in a batch (
batch_size≥ 0).
