Has anyone here heard about Zernike orthogonal polynomials?
Well, I have a problem of computing fitting coefficients for a set of data.
In details, I'm given an array with some values defined on the cirlce at the certain points inside this circle. I need to approximate this data with Zernike polynomials.
Well I just need a person who could describe me a step-by-step algorithm.
I'm ready to give additional information.
Probably, this explanation is not quite full, but.... that's all I can express in English for this moment.
:rolleyes: :confused: Here is more info about Zernike polynomials
