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: make_connected.m
    path of file: ./repos/CanlabCore/CanlabCore/External/matlab_bgl
    
    the code of the file until where you have to start completion: function varargout= make_connected(A,varargin)
% MAKE_CONNECTED Add edges to construct a connected graph
%
% C = make_connected(A) generates a new graph C with additional edges
% to make C connected.  
%
% [ei,ej] = make_connected(A) returns the additional edges instead.
%
% ... = make_connected(A) takes a set of
% key-value pairs or an options structure.  See set_matlab_bgl_options
% for the standard options. 
%   No additional options for this function
%
% Example:
%   G = sparse(2,2); % empty 2 node graph with 2 components
%   C = make_connected(G)
%   max(components(C))
%
