This is what I was going to mention. Vectorize is built on top of frompyfunc which lets you create "object-array" ufuncs from python functions. All ufuncs have an accumluate method. -Travis _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
