I have a large number of cfit smoothing spline objects. The object normalises the input data before applying the coefficients. How can I extract the normalisation constants (0.4671 and 0.3831 in the example).

cfit0 = 
     Smoothing spline:
       cfit0(x) = piecewise polynomial computed from p
       where x is normalized by mean 0.4671 and std 0.3831
     Coefficients:
       p = coefficient structure
