That's a shame, minus infinity is the identity for maximum too.

Hmm. Well, I tried implementing logsum()

Basically, you need 3 arrays: functions

I've not used it, but have a look at numpy.
Hi,
Suppose I have a C function,
double logsum(double a, double b);
What is needed to produce a ufunc object whose elementwise operation
is done by calling this function?
Also, is there a way to take a python function and automatically make
a ufunc out of it? (No, vectorize doesn't implement redu
