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: acot.m
    path of file: ./repos/chebfun/@chebfun
    
    the code of the file until where you have to start completion: function F = acot(F, varargin)
%ACOT   Inverse cotangent of a CHEBFUN.
%   ACOT(F) computes the inverse cotangent of the CHEBFUN F.
%

    
function F = acot(F, varargin)
%ACOT   Inverse cotangent of a CHEBFUN.
%   ACOT(F) computes the inverse cotangent of the CHEBFUN F.
%
%   ACOT(F, PREF) does the same but uses the CHEBFUNPREF object PREF when
%   computing the composition.
%
% See also COT, ACOTD.

% Call the compose method:
F = compose(F, @acot, varargin{:});
