as @dasdingonesin already wrote, you need to use the symbolic toolbox like this: syms x y z; f = [x+2*y+z, x^3+y^2+3*z]; gradf = jacobian(f, [x,y,z]).

The objective function is simple enough that you can calculate its Jacobian. Following the definition in Jacobians of Vector Functions, a Jacobian function represents the matrix J k j ( x) = ∂ F k ( x) ∂ x j. Here, F k ( x) is the k th component of the objective function. This example has F k ( x) = 2 + 2 k - e k x 1 - e k x 2, so

17.02.2013 · Once you calculate the symbolic expression of the Jacobian of the given matrix, you can find the numeric value of the Jacobian matrix using the subs command.In this case if r l and f have a value of 1, we can do: J=subs (J, {r,l,f}, {ones (3,1)},0); 0 Comments Sign in to comment.
