jc_0804: Prohibited use of recursive calls with graphical functions

Since R2020a

Guideline Publication

Control Algorithm Modeling Guidelines - Using MATLAB^®, Simulink^®, and Stateflow^®

• Version 6.0

Sub ID Recommendations

• NA-MAAB — a

• JMAAB — a

MATLAB Versions

All

Rule

Sub ID a

Calls from a graphical function to itself and calls between graphical functions shall be prohibited.

Custom Parameter

Not Applicable

Example — Correct

Processing is performed within the graphical function.

Example — Incorrect

The graphical function is calling itself.

Graphical functions are calling each other.

Rationale

Sub ID a:

• Readability decreases. Deviation from the rule can cause unintended overflows and infinite loops.

Verification

Adherence to this modeling guideline cannot be verified by using a Model Advisor check. For more information, see Check usage of graphical functions in Stateflow (Simulink Check).
