This is the code:
function [z] = Stereo( directory, imagename, numImages)
% ***********************************************************************
% Read the lights and directions:
% ***********************************************************************
lightfile = strcat( directory, '/', 'lights2.txt')
fid = fopen(lightfile, 'r');
numLights = 1;
numLights = fscanf(fid, '%d \n', [1]);
LightMatrix = [];
for i = 1:numLights
lightDir = fscanf(fid, '%f %f %f \n', [3]);
lightDir = lightDir/norm(lightDir);
lightMatrix(i,:) = lightDir;
end

You're getting this error because the path to your file is not correct.
this is where the problem is:
lightfile = strcat( directory, '/', 'lights2.txt')
Print/Display this variable to see the path to the file.
BTW, if your file is structured like in the posted image, I suggest to use readmatrix function instead of fopen and fscanf.
