You could try Piecewise and make certain you know proper Mathematica syntax.
A more specific and complete posting might give rise to a more complete answer.

Hi, I have a function on the plane that has 2 different formulation for 2 different regions. Let x = (x1, ..., xn). I want to define it as
U(x) = U_1(x) if x is in region 1 = U_2(x) if x is in region 2
Then I want to analyze such a defined function, like find its max, etc, using NMaximize, or put in some other expressions in place of x, to see behavior of U.
Essentially, how does one define a multipart function, so that we can analyze it in the same way we may analyze a single part function or polynomial?
Thanks.
Prabhu
