MATLAB: Arbitrary sized function evaluation

function handlevectorization

x is an n-dimensional vector, and f is a function which takes in n variables. Is there a way to dynamically evaluate f so that the number of variables does need to be pre-specified? For example, I would like a single piece of code where if n equal three, would give me f(x(1), x(2), x(3)), and if n = 4, would give me f(x(1), x(2), x(3), x(4)). Any help on this matter would be greatly appreciated.

  • xt = num2cell(x);
    f(xt{:});
