Zernike fitting, given a list of 3D points (x,y,z).

[sidgairo18]

How can we use the fitting function if we are given a 3D point cloud of (x,y,z) values where z is the elevation at point (x,y)?
It is not very apparent from the code.
Your help would be appreciated.

Thank you.

Yon only need to input Z if the center of the surface is (0,0). In code, the x,y are [-1,1]. Before you input your Z, maybe you need to adjust(scale) the data. I will suggest using some other code/programs to do the fitting if you are doing some serious project. These fitting codes are mainly for my own practice 5 years ago. Thanks!
