Maximum identifier length




l = namelengthmax returns the maximum length allowed for MATLAB® identifiers. MATLAB identifiers include:

  • Variable names

  • Structure field names

  • Script, function, and class names

  • Model names

Use the namelengthmax function instead of hard-coding a specific maximum name length into your programs. Then, if the identifier length changes in a future MATLAB release, it is not necessary to update this limit in your code.

Introduced before R2006a
