Check for inconsistent vector indexing methods

Check ID: mathworks.hism.hisl_0021

Identify blocks with inconsistent indexing method.


Using inconsistent block indexing methods can result in modeling errors. You should use a consistent vector indexing method for all blocks. The indexing methods are zero-based, one-based or user-specified.

Blocks that support configurable indexing:

Blocks that support only one-based indexing:

Blocks that supports only zero-based indexing:

  • Stateflow chart with C action language

  • Truth Table function with C action language

  • State Transition Table (Stateflow) with C action language

Available with Simulink® Check™.

Results and Recommended Actions

ConditionRecommended Action
The model or subsystem contains blocks with inconsistent indexing methods. The indexing methods are zero-based, one-based or user-specified.Modify the model to use a single consistent indexing method.

Capabilities and Limitations

  • Runs on library models.

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

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

  • Allows exclusions of blocks and charts.
