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: outlinebounds.m
    path of file: ./repos/d2d/arFramework3/MatlabTools
    
    the code of the file until where you have to start completion: function hnew = outlinebounds(hl, hp)

    
function hnew = outlinebounds(hl, hp)
%OUTLINEBOUNDS Outline the patch of a boundedline
%
% hnew = outlinebounds(hl, hp)
%
% This function adds an outline to the patch objects created by
% boundedline, matching the color of the central line associated with each
% patch.
%
% Input variables:
%
%   hl:     handles to line objects from boundedline
%
%   hp:     handles to patch objects from boundedline
%
% Output variables:
%
%   hnew:   handle to new line objects

hnew = zeros(size(hl));
for il = 1:numel(hp)
    col = get(hl(il), 'color');
    xy = get(hp(il), {'xdata','ydata'});
    ax = ancestor(hl(il), 'axes');
    
    hnew(il) = line(xy{1}, xy{2}, 'parent', ax, 'linestyle', '-', 'color', col);
