Hi, I am trying to call a m file from Simulink. I have to use set_param in my code in MATLAB function block, but I am getting this error: Function 'set_param' is not supported for code generation. Consider adding coder.extrinsic('set_param') at the top of the function to bypass code generation.

any idea?

Hi there,

Use

coder.extrinsic('set_param')

before declaring set_param in function.

Example

function fcn(path_c, parameter_c, value_c, path_h, parameter_h, value_h)
coder.extrinsic("set_param")
set_param(path_h, parameter_h, value_h);
set_param(path_c, parameter_c, value_c);
coder.extrinsic('fcn')
end
