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: findendsjunctions.m
    path of file: ./repos/Image-Harmonization-Dataset-iHarmony4/Lalonde and Efros/utils/3rd_party/pkovesi/LineSegments
    
    the code of the file until where you have to start completion: % FINDENDSJUNCTIONS - find junctions and endings in a line/edge image
%
% Usage: [rj, cj, re, ce] = findendsjunctions(edgeim,
    
function
    % defined at the end of this file to test that the centre pixel within a 3x3
    % neighbourhood is a junction.
    lut = makelut(@junction, 3);
    junctions = applylut(b, lut);
    [rj,cj] = find(junctions);
    
    % Set up a look up table to find end
