Ok, in trying to also convert "median" to use NDArrays, I've come back to the problem of converting "sort" first, as median uses the "sort"
... This is somewhat off-topic. Technically one does not need to do a full sort to get a median. I am just wondering how straightforward would it be to modify 'sort' to just pickup the N-th element? E.g. there is "select()" algorithm in the "Numerical Recipes" which was faster than glibc's qsort() when I tried it.
