from scipy import * from RandomArray import * from numarray import *

I believe the problem is in this part. You are getting some functions (like rand) which return a numeric array which some numarray functions don't recognize (we will be fixing this soon, they should accept any Python sequence that fits the basic requirements). For the moment you will need to generate a numarray array for that function to work. In the latest release you would do the imports as follows (for version 0.6 and later) from numarray.numeric import * from numarray.random_array import * a = random((5,5)) and so forth Perry
