It's just the usual formula, the sum(x .* intensity) / sum(intensity). It's like the intensity cancels out and you're left with the weighted x value.

How can I do it to all the rows in a image and save it

oneRowIntensity = image2D(theRowYouWant, :);
x = 1:size(image2D, 1);
Then use the formula I gave you, and save it using save() or imwrite() or into a variable. Put that into a loop if you want to do it for all the rows that you want to do it over.
