Check nested conditions in MATLAB Functions

Check ID: mathworks.jmaab.na_0018

Guideline:

• MAB v6.0 na_0018: Number of nested if/else and case statement

• JMAAB v6.0 mp_0016: Nesting levels of control statements

Description

Checks for number of inputs/outputs to a Variant Subsystem.

This check requires a Simulink^® Check™ license.

Check Parameterization

This check does not include sub-checks because the MAB modeling guideline provides only one sub ID.

For reference, the MAB guideline sub ID(s) that are recommended for use by the NA-MAAB and JMAAB modeling standards organizations are:

• NA-MAAB — a

• JMAAB — a

Under Input Parameters, select Check external .m files referenced in the model to include files with a .m extension in the analysis.

Results and Recommended Actions

Condition	Recommended Action
One or more MATLAB Function found with deeply nested if/else and case statements.	Remodel to reduce the number of deeply nested conditional statements.

Capabilities and Limitations

• This check also implements the JMAAB v6.0 guideline: mp_0016

• Runs on library models.

• Analyzes content of library linked blocks. By default, the input parameter Follow links is set to on.

• Analyzes content in masked subsystems. By default, the input parameter Look under masks is set to all.

• Allows exclusions of blocks or charts.
