I think he meant do an argsort first, then use fancy indexing to get the sorted array. For a 1-d array that's just ind = A.argsort() Asorted = A[ind] That should be O(N lg N + N), aka O(N lg N) For A >1-d, you need an indexing expression that's a little more complicated, hence the discussion about making an "extract" function for that purpose. Then you could say: ind = A.argsort(axis=d) Asorted = A.extract(ind,axis=d) and it should just work no matter what 'd' is. --bb ------------------------------------------------------------------------- Take Surveys.
