Keywords

MATLAB reserves certain words for its own use as keywords of the language. To list the keywords, type

• iskeyword
  
  ans = 
  
      'break'
      'case'
      'catch'
      'continue'
      'else'
      'elseif'
      'end'
      'for'
      'function'
      'global'
      'if'
      'otherwise'
      'persistent'
      'return'
      'switch'
      'try'
      'while'
  

See the online function reference pages for help to learn how to use any of these keywords.

You should not use MATLAB keywords other than for their intended purpose. For example, a keyword should not be used as follows:

• while = 5;
  ??? while = 5;
            |
  Error: Expected a variable, function, or constant, found "=".
