The function 'wrcoef' is not supported for standalone code generation in Simulink

Hello, i wrote a user defined matlab-function for a simulink model where the function 'wrcoef' is called. The simulink diagnostic viewer displays the error: 'The function 'wrcoef' is not supported for standalone code generation. See the documentation for coder.extrinsic to learn how you can use this function in simulation.'

Has anybody some advice how to use coder.extrinsic to solve that problem?

Hi Ali,

I understand that you are using wrcoef in MATLAB function block and facing issues.

You can use code.extrinsic as illustrated in the following example:

function c = pythagoras(a,b,color) %#codegen
% Calculates the hypotenuse of a right triangle
%  and displays the triangle as a patch object. 

c = sqrt(a^2 + b^2);

create_plot(a, b, color);

function create_plot(a, b, color)

%Declare patch as extrinsic
coder.extrinsic('patch'); 

x = [0;a;a];
y = [0;0;b];
patch(x, y, color);
axis('equal');

If you have already tried this approach, please share the issue/error you encounter if any.

Here you can find the complete list of functions supported for code generation.
