Check input and output settings of MATLAB Functions

Check ID: mathworks.maab.na_0034

Guideline: na_0034: MATLAB Function block input/output settings

• MAB v5.0

• JMAAB v5.1

• JMAAB v6.0

Description

The check identifies MATLAB^® Functions with inherited complexity or data type properties. A results table provides links to MATLAB Functions that do not pass the check, along with conditions triggering the warning.

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

Results and Recommended Actions

Condition

Recommended Action

MATLAB Functions have inherited interfaces with one or more of these conditions: Complexity is Inherited. Type is Inherit: Same as Simulink. Size is —1 (Inherited).

Explicitly define complexity and data type properties for inports, outports, and parameters of MATLAB Function identified in the results. If applicable, using the MATLAB Function Block Editor, make the following modifications in the Ports and Data Manager: Change Complexity from Inherited to On or Off. Change Type from Inherit: Same as Simulink to an explicit type. Change Size from —1 (Inherited) to an explicit size.

Capabilities and Limitations

• Runs on library models.

• Does not analyze content of library linked blocks.

• Analyzes content in all masked subsystems.

• Allows exclusions of blocks and charts.
