Please tell me, how to make this code by using Simulink .
fun=@(x)100*2(x(2)-x(1)^2)^2+(1-x(1))^2;%equation
x0 = [-1.2,1];%start point
x = fminsearch(fun,x0)%using fminsearch
On User-defined Functions,S-Function, I programmed
'fun = @(x)100*(x(2) - x(1)^2)^2 + (1 - x(1))^2;'
For this block, I want to adopt fminsearch on the Simulink in order to find out minimized point[x1 x2]=[1 1].
Sorry, I can't use English well, but I want someone's answer. So if you don't know the meaning of my question, please tell me where don't you know.

Using Interpreted MATLAB Function block is the easiest way to execute fminsearch in Simulink. Write MATLAB Function to call fminsearch, and set the function to block parameter of Interpreted MATLAB Function.

Hi Yoko Miyazaki, I also want to use fminsearch in Simulink,but i need to build the model(code generate).So, interpreted MATLAB Functino does not work.Is there any other method that i can solve this problem? many thanks.
