Hello,

In MATLAB functions, if you would like to use a variable from the workspace rather than the ones passed as function arguments, you can use the "evalin" function with the first argument as 'base'.

Link to the documentation:

https://www.mathworks.com/help/matlab/ref/evalin.html

Here's a code snippet:

pmsm = evalin('base', 'pmsm');
p1 = 3 * pmsm.pp;

Thank you for your reply, but used your suggestion.

Matlab gave me another ERR Report.

For code generation, I don't think "evalin" is supported because there is no such concept of a workspace once the code is generated in C. It is expected that the function arguments or any global variables are the ones that are being used within the function.
