Greetings, I'm not sure if I'm using the most up to date version of Numeric but... num_array ** 2 doesn't work if num_array is Float32 (Float64 works fine). Has this been fixed in a more recent release? -bsd- _______________ MATRIX-SIG - SIG on Matrix Math for Python send messages to: matrix-sig@python.org administrivia to: matrix-sig-request@python.org _______________
