min(f,g) where f and g take two variables

Is it possible to create a function h(x,y) that would be the minimum (or maximum) of any two other 2-variable functions?

Like h(x,y)=max(f(x,y),g(x,y))? (this does not work)

This seems to be a rather useful function but I can't seem to find it.

any ideas?

Thanks N.

Just for reference for those finding this, this is nearly the same question as ... which apparently you asked? (It says anonymous but you replied later.) I'm wondering if maybe we misinterpreted one of your questions and gave a less than useful answer.

For example:

sage: h(x,y)=max_symbolic(x^2-y^2,y^2-x^2)  
sage: plot3d(h(x,y),(x,-1,1),(y,-1,1))
