Thank you, Robert! numpy.seterr() is very helpful. It is just what I needed. numpy.seterr(all = 'raise') forces numpy to raise exceptions instead of printing warnings. [begin quote] numpy.seterr(all = None, divide = None, over = None, under = None, invalid = None) Valid values for each type of error are the strings "ignore", "warn", "raise", and "call".

numpy.seterr() Read the docstring for the various options. -- Robert Kern
