How to convert a symbolic piecewise function into a matlab function with a function handle?

I have a symbolic expression (of two variables) that is a product of 3 symbolic expressions where one of those is a piecewise function. I need to do a numerical integration (with int) over one of the variables while the other variable should be ArrayValued. However, this does not work with a symfun and I cannot use matlabFunction() to convert it because of the piecewise functions.. Any ideas would be much appreciated.
