I have two columns with the x and y coordinates for the Actual and the estimates .How do I find the RMS error for each of the elements in the columns ?

RMSEx = sqrt(mean((gt_track_spatial(:,1) - Int_point(:,1)).^2));

RMSEy = sqrt(mean((gt_track_spatial(:,2) - Int_point(:,2)).^2));

This is my code, but it just returns one value for RMSEx and RMSEy.

How to return a vector for the rms values for the x and y coordinates for each of the elements in the columns?

len_dat = size(gt_track_spatial,1);
for i = 1:len_dat
    RMSEx(i) = sqrt(mean((gt_track_spatial(i,1)-Int_point(i,1))^2));
    RMSEy(i) = sqrt(mean((gt_track_spatial(i,2)-Int_point(i,2))^2));
end
