Guideline Publication
Control Algorithm Modeling Guidelines - Using MATLAB®, Simulink®, and Stateflow®
Sub ID Recommendations
NA-MAAB — a, b
JMAAB — Not supported
MATLAB Versions
All
Rule
Sub ID a
Reserved C variable names shall not be used as variable names in MATLAB code. For example, avoid using const,
TRUE, FALSE, infinity,
nil, double, single, or
enum in MATLAB code.
Not Applicable
Sub ID b
Variable names that conflict with MATLAB functions, such as conv, shall not be used.
Not Applicable
Rationale
Sub IDs a, b:
Improves readability of the code
Code generation may not be possible.
Note
The MATLAB limit for the number of characters you can use in variable names is 2048.
Verification
Model Advisor check: Check usage of restricted variable names (Simulink Check)
