Yes, you need to specify which axis you want to sum over if you have a multi-dimensional array. This is the "basic" behavior of most functions in numpy unless you import them from oldnumeric. See the fix_default_axis.py file for help on converting code that worked for numpy 0.9.8 to 1.0 where this switch was made. -Travis ------------------------------------------------------------------------- Using Tomcat but need to do more?
