How can I give a predefined function as a parameter in a new function?

I want to calculate if any arbitrary signal is an energy signal or a power signal. Is there a way in which I can give the function as a parameter for the energy/power finding function so that I can find the energy/power of any signal without changing the code?

You can pass function handles as arguments.

Example:

    function h = wave(x)
        h = sin(2*pi*sin(x));
    end

    function y = rms(fun,x)
        y = sqrt(mean(fun(x).^2));
    end

x = linspace(0,2*pi);
y = rms(@wave,x);

fprintf(1, '\n\tPower = %f\n', y)

This code produces:

  Power = 0.645782
