I have five, very precise, experimental values of refractive index for five different wavelengths and would like to draw the Sellmeier fit of the form:(adsbygoogle = window.adsbygoogle || []).push({});

n^2=A1+A2/(1-A3/lambda^2) + A4/(1-A5/lambda^2)

So, to find A1, A2, A3, A4 and A5 parameters I need to solve the system of five equations. Those equations are nonhomogenous. I would like to use Matlab program to solve that, but I don’t know which function and which form to use…Anybody already solved this? Thanks!
