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.
