> LENGTH is somewhat tricky since it returns the largest of the sizes in all dimensions. It can become nasty to debug errors when you supply matrices instead of vectors.
> I always use NUMEL to find the number of elements, which is as clear as it can get.
> Although I do not know the internal processes going on in LENGTH and NUMEL, I assume that LENGTH requires more internal steps.
