How do I pas one scalar from a function that outputs an array?

I have a function that does this:

    function [A, B, C] = func(x)
A = x^2;
B = x^3;
C = x^4;
  end

I want to pass it in another function like this:

ans = func2(@func,xx)

But I only want to pass B; not A or C. How do I go about doing this? Thanks

Is no Matlab syntax to do that directly; use an intermediate temporary variable to hold the result.

If must have a function handle the best I can think of is would have to have a wrapper function around the original that returns only the desired output.
