    • The funcdemo function:
      

      function [] = funcdemo( msg )
          fprintf( 'Your message is "%s"\n', msg );
      end

    • Some uses of it:
      

      >> funcdemo( 'Hello!' )
      Your message is "Hello!"
      >> M = 'This is some text';
      >> funcdemo( M )
      Your message is "This is some text"
      >> funcdemo( [ 'Hello! ', M ] )
      Your message is "Hello! This is some text"
      >> funcdemo
      {Error using funcdemo (line 2)
      Not enough input arguments.
      }
