POLYFIT  POLYFIT Fit Polynomial To Data


Usage
 
 The polyfit routine has the following syntax
 
   p = polyfit(x,y,n)
 
 where x and y are vectors of the same size, and
 n is the degree of the approximating polynomial.  
 The resulting vector p forms the coefficients of
 the optimal polynomial (in descending degree) that fit
 y with x.
