Could someone explain what is the problem?
The problem is on the line #7
datavalues = dlmread(tline);
tline = fgets(fid);
index = str2num(tline);
datacoord = datavalues(:,index);
tline = fgets(fid);
index = str2num(tline);
datavalues_hard = datavalues(:,index);
tline = fgets(fid);
index_reg = str2num(tline);
end

Try to use breakpoints to check the value of index.
