That would be useful only if the matrix class wasn't storing individual
matrices but a large number of them. Both for GPU and CPU uses. I don't think
you want to iterate over an NSArray to do matrix multiplication or transposes
individually.
As intended, GPUs and CPUs probably accelerate matrices up to 4x4, so I don't
think they apply to a general purpose matrix either (maybe I am wrong).
It's hard to advise Dale without knowing the specific use case.
