'dare' command from Control toolbox doesn't work in the Simulink's 'Matlab Function' block

'dare' command can work in the script and the real-time script, but it can not work in the Simulink's 'matlab function' block;
I have checked the license of the 'Control_Toolbox', it returns to 'answer = 1'.
Error infos are:
'Function 'dare' not supported for code generation. '
'Function 'MATLAB Function' (#23.726.769), line 28, column 1: "[P,L,M]=dare(Tilde_A,Tilde_B,Tilde_Q,R,S,E)" Launch diagnostic report.'
Appreciate for any advice!

Note that you should probably be using the / or \ operator instead of inv() with a matrix multiplication

In the Matlab Function block, declare dare with coder.extrinsic. See this doc page

This will not solve the problem if Rapid Accelerator is turned on, or if code is being generated such as for deploying to arduino. In those cases the solution is to write your own equivalent to dare()
My first thought is also writing a direct riccati_solver, I do this just for simulation. So I may try coder.extrinsic as well.
Thank you Paul and Watler!
