numarray newbie

Hi,

This is more of a numarray issue, but also relevant here I hope. I
wonder how you sort a numarray.array descending? I know
numarray.sort(array) sort ascending.

thx

"numarray.sort(array)[-1::-1]" should work for reversing the list fairly fast.
That indexing btw means start at the last item, and use a stride of -1.

There is a special mailing list for this sort of question (numpy-discussion@lists.sourceforge.net). There are a number of ways one can do this but why not either reverse the sorted array (or the sorted indices) by using strides, e.g., get the sorted array and then refer to it as sarr[::-1]?
