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.
