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_biconnected_planar.m
    path of file: ./repos/CBIG/external_packages/matlab/default_packages/matlab_bgl_mac64
    
    the code of the file until where you have to start completion: function varargout= make_biconnected_planar(A,varargin)
% MAKE_BICONNECTED_PLANAR Add edges to construct a biconnected planar graph
%
% M = make_biconnected_planar(A) generates a new graph M with additional edges
% to make M biconnected.  A biconnected planar graph stays connected even
% if any edge is removed.
%
% [ei,ej] = make_biconnected_planar(A) returns the additional edges instead.
%
% ... = make_biconnected_planar(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 = grid_graph(6,1); % generate a line graph
%   B = make_biconnected_planar(G);
%   biconnected_components(B)
%   max(components(B))
%   B(1,2) = 0; B(2,1) = 0;
%   max(components(B)) % still one component
