Dear everyone,
I am a beginner of Gwyddion.
I have some AFM images of quantum dots. Now I want to change their height
axes (Z axes) to be -abs(sqrt(dz/dx^2 + dz/dy^2)), where z(x,y) is the
topograph and dz/dx, dz/dy are numerical derivatives along the two image
axes.
After reading the user guide, however, I still cannot find the answer for
this question.
who can help me? thank you very much!
