Stateflow Onramp - Functions in Stateflow 9.3 - Matlab functions - Bug ? Error: Illegal use of reserved keyword "end".

Hello,

I'm following the course Stateflow Onramp and I can't valid the module number 9.

Here's the thing, when I'm done writing the code of a matlab function I click on the submit button and I get the following error :

"Error evaluating 'StopFcn' callback of block_diagram 'StateflowOnramp'.

Callback string is 'learning.simulink.modelCallbacks.stopFunction(gcs)'

Caused by:

Error: Illegal use of reserved keyword "end". "

No matter what I do afterward the submit button is frozen. I attached a screenshot to help figure out what going on.

Also I did try on both the online version of Matlab and the desktop one.

Best regards,

Soufiane

Hello Soufiane,

As explained in the Section 9.1 of Stateflow Onramp, the syntax of a MATLAB function within stateflow doesn't include 'end' keyword to be used at the end of function. You could try executing the code by removing the 'end' keyword within the function. For more information you could have a look at the following documentation page:

Define MATLAB Function in a Chart

Hope this helps!

Thanks you very much. It was indeed the case, the syntax of a MATLAB function within stateflow differ from a normal MATLAB function. I've been able to complete the course.
