namelengthmax - Maximum identifier length - MATLAB (original) (raw)

Main Content

Maximum identifier length

Syntax

Description

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.
