A few years back I wrote a Mathematica notebook that shows how one can obtain
the SG smoother from Gram polynomials. The code is not very elegant; but, it is
a rather general implementation that should be easy to understand.

Contact me (v...@it.uu.se) if you are interested and I will be glad to forward the
notebook to you.
