MATLAB: How to add power of x from 0 to n-1

vandermonde matrix power linear system of equations

I have a function vandermonde
function c = vandermonde(x, y)
    V = [x.^0 x x.^2 x.^3]  
    c = V \ y;
end
it works good if I give a vector x with 4 components. But how could I make it general, even if I give a vector x with 5,6 or even 15 components? so that V = [x.^0 x x.^2 x.^3 x.^4 x.^5 …. x.^14] ? with n or something like that?

Best Answer

   V=bsxfun(@power,x(:),0:n-1)
