23 Oct 2013 Abel Inversion Algorithm Fourier-based reconstruction of an unknown radial distribution assuming cylindrical symmetry. Author: Carsten Killer

I tested this inversion against 3 known analytical abel pairs and found good agreement with this numerical solution. I found that with smooth data with good signal/noise, increasing upf provided a better answer.

I was able to get the code working by replacing lsqcurvefit with a standard non-linear equations solver and simply supplying the residuals. Everything seems to be ok but I still need to through a few theoretical test curves at it. Thanks!

Worked flawless for my application, cheers.

Would it be possible to use this code without having the optimization toolbox (lsqcurvefit function)? Does it simply find a scaled coefficient for each of the vectors?
