Hi guys, I got to analyse image that is created by Atomic Force Microscope so contains different height values. But I want to make sure I implement these equations correctly, can somebody please help. Would be much appreciated.
Best regards, Matiss

If you have your height values in a 2D matrix Z, use
sa = mean2(abs(Z));
sq = sqrt(mean2(Z.^2))
sz = max(Z(:)) - min(Z(:))

@Matiss - you need to divide by area if you want normalized numbers. You can be rest assured these results from code by @Thorsten is only off by a constant scale factor (of area of image in question with additional fixed constants) from this other software you are mentioning.
