Re: [Scilab-users] Multiple regression on semi-log plot

Hello, Thanks for showing how it works, always good to get a proper understanding. Just wondering if the code can be adapted to find multiple straight line segments? Looking at my original test data, it appears to have "kinks" at wavenumber (0.05, 0.12 and 0.16), the last one is where the x
