Check ID: mathworks.jmaab.ar_0002

Guideline: ar_0002: Usable characters for folder names


Checks if folder names adhere to the following guideline standards.

  • Do not begin with a number.

  • Do not begin or end with an underscore.

  • Do not contain consecutive underscores.

  • Do not coincide with reserved MATLAB® words.

  • Contain only alphanumeric characters and underscores.


Reserved MATLAB words include the following:

This check requires a Simulink® Check™ license.

Check Parameterization

This check contains sub-checks that correspond to sub IDs specified in the MAB and JMAAB modeling guidelines. You can use the Model Advisor Configuration Editor to specify which sub IDs (one or multiple) to execute.

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, b, c, d, e, f

  • JMAAB — a, b, c, d, e, f

Capabilities and Limitations

  • Use the input parameter Allow MATLAB namespace to allow folder names to begin with the special characters, + or @.

  • Use the input parameter Check hidden folders to run the check on hidden folders.

  • Runs on library models.

  • Runs on nested sub directories.
