Check for MATLAB Function interfaces with inherited properties

Check ID: mathworks.hism.himl_0002

Identify MATLAB® Functions that have inputs, outputs or parameters with inherited complexity or data type properties.


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.

Available with Simulink® Check™.

Results and Recommended Actions

ConditionRecommended Action
MATLAB Functions have inherited interfaces.

Explicitly define complexity and data type properties for inports, outports, and parameters of MATLAB Functions identified in the results.

If applicable, using the MATLAB Function Block Editor, make the following modifications in the Property Inspector:

  • Change Complexity from Inherited to On or Off.

  • Change Type from Inherit: Same as Simulink to an explicit type.

Capabilities and Limitations

  • This check only analyzes the functions that are directly referenced by the Simulink model.

  • 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 and charts.
