I'm not a Matlaber, but Mathwokr websit tells me this is used for polynomial fitting

http://www.mathworks.fr/fr/help/matlab/ref/polyfit.html

In fact, you don't need a specific function as polynomial fitting is just a multiple linear regression considering each x^n is a variable
(in this case, the variables are strongly correlated contrarily to usual multiple linear regression)

Please read the following discussion where I explain how to perform a polynomial fit
