function g = gradfun(fun,x)
% gradfun('fun',x) evaluates the gradient of the function 'fun' at the
% point x = [x1,..., xn]. This function uses complex differentiation.
%
% Example:
%
% f = @(x) 10*cos(x(1))*sin(x(2)) + x(1)^2 - 2*x(2)^2 + 10;
% x0 = [pi; -pi];
% g0 = gradfun(f, x0)
%
% Returns the value of the gradient of f at x0, which is [6.2832; 22.5664].
