Neural Network to approximate function

Hello I am trying to create a Neural Network to predict a function (Rosenbrock function). I desire to use the toolbox provided by MATLAB but i don't know which function to use. Can someone help me? The Rosenbrock function looks like this: Hope someone is willing to help me.

Hi Tobias,

The “rosenbrock” function is provided within the Deep Learning toolbox. Here is the code for the same:

function [y,dydx] = rosenbrock(x) 
    y = 100*(x(2) - x(1).^2).^2 + (1 - x(1)).^2; 
    dydx = dlgradient(y,x); 
end
