Hi All,
I'm thinking of adding some new ufuncs. Some possibilities are
- expadd(a,b) = exp(a) + exp(b) -- For numbers stored as logs:
- absdiff(a,b) = abs(a - b) -- Useful for forming norms
-
absmax(a,b) = max(abs(a), abs(b))
- absadd(a,b) = abs(a) + abs(b) -- Useful for L_1 norm and inequalities?
I would really like a powadd = abs(a)**p + abs(b)**p, but I can't think of an easy way to pass a variable p that is compatible with the way ufuncs work without going to three variables, something that might not work with the reduce functions. Along these lines I also think it is time to review generalized ufuncs to see what we can do with them. Thoughts?
