Dear Researchers,
I have two entities namely sigma (dB) and U (m/s) respectively. As given in attach figure, a linear least squares is used to fit among two entities. I have attached .mat files which contains sigma and U values. I need to fit this curve to analyse Bias and RMS.
I lookforward to receive your valubale suggestions.
Thank you!

That certainly doesn't look to be nonlinear. What's the functional form you think you should be fitting (a literature reference to the type of data/from whencecame the above figure, maybe???)
