You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: fliplr.m
    path of file: ./repos/chebfun/@classicfun
    
    the code of the file until where you have to start completion: function f = fliplr(f)
%FLIPLR    Flip columns of an array-valued CLASSICFUN object.
%   FLIPLR(F) flips the columns of an array-valued CLASSICFUN F in the left/right

    
function f = fliplr(f)
%FLIPLR    Flip columns of an array-valued CLASSICFUN object.
%   FLIPLR(F) flips the columns of an array-valued CLASSICFUN F in the left/right
%   direction. If F has only one column, then this function has no effect.
