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

Stateflow block shall not use numeric literal.

Exceptions

• Initial value is 0

• Increment, decrement 1

Custom Parameter

Not Applicable

Example — Correct

Numeric literals are not used.

Example — Incorrect

Numeric literals are used.

Rationale

Sub ID a:

• Only the modeler will understand the purpose of the value when numeric literals are used to write constants, which decreases readability.

• Constants that are intended for calibration are generated in the code using numeric literals.

Verification

Model Advisor check: Check usage of numeric literals in Stateflow (Simulink Check)
