Dear community,

i wondering if there is a way to get the name of the input signal of a "matlab function"-block.

That´s what my model looks like:

I already tried the get_param(u,...) to get the signal name but it didn´t work as the following error occurs: "Function 'get_param' not supported for code generation."

Is there any way to solve this?

Thanks for your help!

If you are still trying to do that testing about nan, remember that code cannot do dynamic fieldname access in generated code; https://www.mathworks.com/matlabcentral/answers/506792-is-it-possible-to-access-struct-fields-dynamically-in-generated-code#answer_416689

so even if you can get the signal names in generated code, you cannot loop over the names in generated code to test the bus elements by name.

I do not know, sorry. Material I found earlier implied that in compiled code, the signal names are not available.

Thanks for your help. Maybe someone else finds a solution :)

Have a nice day!
