Thickness of height profile in Matlab

Hi,

I have aploted AFM height profiles from images using plot fuction in matlab.

I also need to find the difference or thickness from these height profiles, Is there a way I can do that in Matlab.

Here is what I have so far

This image has two height profiles and I can plot the maximum and minimum data lines for the profile.

I also need the difference on the plot. This is what I want (I use power point for this)

I have attached the code I use. Any help will be appreciated.

Thank you.

Try this

% to plot vertical line 
xAxis=1.25
ymin=B % min point 
ymax=A %max point
line([xAxis xAxis], [ymin ymax]);
% add text
txt = 'Thickness';
text(xAxis+1,C/2,txt)
