I am having trouble writing this equation out in matlab, am a beginner. This is my attempt so far: CS= sum(((y-m)./err_y).^2). Any help would be much appreciated!

As long as y, m and err_y have the same number of elements then your expression should work ok.

It is reasonable that the better fitting model produces a smaller value of chi-squared.
Your expression for chi-square looks somewhat unusual to me
(see https://www.statisticshowto.com/probability-and-statistics/chi-square/ for example), however, I'm no statistics expert.
