Hello, I am trying implement a function that contains the factorial operator: n! = (n)(n-1)(n-2)...(1), where n is a positive integer.

I cannot find this in the "Operators, Functions, and Constants" section of the Reference Manual. Does COMSOL have this mathematical operator built-in?

Answered my own question: Use the implemented gamma function, as gamma(n+1)
