uncomplicate.neanderthal.auxil
Contains type-agnostic auxiliary functions roughly corresponding to the functionality
usually defined in auxiliary LAPACK (sorting etc.), or useful functions that may not commonly be
implemented by BLAS engines, but are helpful vectorized ruoutines. This namespace works similarly
to uncomplicate.neanderthal.core; see there for more details about the intended use.
Cheat Sheet
