/* the direct sgemm code written by Arjan van der Ven */

/*
|
||||
* "Direct sgemm" code. This code operates directly on the inputs and outputs
|
||||
* of the sgemm call, avoiding the copies, memory realignments and threading,
|
||||
* and only supports alpha = 1 and beta = 0.
|
||||
* This is a common case and provides value for relatively small matrixes.
|
||||
* For larger matrixes the "regular" sgemm code is superior, there the cost of
|
||||
* copying/shuffling the B matrix really pays off.
