If you're using MATLAB app designer, it will be easier if you click the 'add a function' button and define your multiply there itself (I see no reason to do it in a separate script). Note: If you add it as a private method, use app.multiply() everywhere.

Given that you only know the name, it would be a bit odd to assume the functionality is the exact same as *.
Maybe this is what that function does:
function af=multiply(x,y)
af=@(c) x*y + c;
