Python's built in pow() and exp() functions can't handle numpy arrays, and thus try (and fail) to convert arrays to scalar values. You want to use numpy.exp and numpy.power (or just the ** operator), to do these operations to numpy arrays elementwise. _______________________________________________ Numpy-discussion mailing list [email protected] http://projects.scipy.org/mailman/listinfo/numpy-discussion
