How to numericaly integrate in simulink-block "matlab function" block

Hello,

I'm trying to use "integral" function in "matlab function" in simulink. You can reduce the code to:

 function f=fun(x)
coder.extrinsic('syms');
coder.extrinsic('integral');
xmin=0
xmax=1
k=@(x)x
syms x
f=integral(k, xmin, xmax)
  end

So when I use this, the error following error occures: "Cannot pass an object of class 'function_handle' to MATLAB function 'integral'". When I try to put in the Function k itself into the integral the error stays the same. When I delete the "@(x)" the Error says that x is not defined.

Can you help me to make the integration work?

thank you

The code you provided seems to work fine for me when I run the code directly in MATLAB.

Please use the below command to ensure that there are no other functions names 'integral' what are being referred to instead of the correct 'integral' function.
