WebApr 3, 2016 · Accepted Answer. Your tests are with symbolic x, but fmincon runs with numeric x. So f = 2*x (1)+3*x (2)^2+exp (2*x (1)^2+x (2)^2) is going to produce a numeric scalar because x (1) and x (2) will have particular numeric values. You then apply the numeric gradient function to that scalar, giving the x (1) and x (2) as the step sizes (which … WebFeb 13, 2024 · Learn more about gradient, symbolic, integration, multi-variable, engineering MATLAB.
