How to take logarithm of a function in matlab?

I have defined a function f=inline('x*y','x','y').That is f(x,y)=x*y.

How can i take log of this function?

logf = @(x, y) log(f(x, y))

But I want to get log(x)+log(y) from taking logarithm of the function (x*y)..MATLAB simply shows log(x*y)

That is a different question that you already asked and I already answered.
