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: complex.m
    path of file: ./repos/chebfun/@chebfun2
    
    the code of the file until where you have to start completion: function varargout = complex(varargin)
%COMPLEX Construct complex CHEBFUN2 from real and imaginary parts.
%   C = COMPLEX(A, B) returns the complex CHEBFUN2 A + Bi, where A and B are
%   real valued CHEBFUN2 objects with the same domain.
%
%   C = COMPLEX(A) for real CHEBFUN2 A returns the complex result C with real
%   part A and all zero imaginary part. isreal(C) returns false.
