How to calculate mean square error between points?

4 views (last 30 days)
Hello everyone. Here I want to calculate the mean square error between the blue dots and the red dot. I'm putting the files. I can't form in my head how to do it. I would be glad if you help.
scatter(reshape(x_T_est1(all(x_T_est1,2),:), [1,numel(x_T_est1(all(x_T_est1,2),:))]), reshape(y_T_est1(all(y_T_est1,2),:), [1,numel(y_T_est1(all(y_T_est1,2),:))]), 'b', 'x'); hold on;
scatter(x_T, y_T, 'r', 'filled');

b=b(~isnan(b(:,1))&~isnan(b(:,2)),:);%you have some NANs in your arrays.

If your scatter plot is working, then the above code should work. I tried in on your attached files (except y_T_est1 not provide, so I set it equal to x_T_est1) and it worked. Not sure what you want to do with the nan values.
