Suppose arr is a two dimensional numarray. Can the following be done entirely within numarray?

alist = arr.tolist() alist.sort() arr = numarray.array(alist, arr.type())

I'm pretty sure the answer is no. The comparisons in numarray's sort() functions are all single element numerical comparisons. The list sort() is using a polymorphic comparison which in this case is the comparison of two lists. There's nothing like that in numarray so I don't think it's possible. Todd
