How to use Savitzky-Golay to do derivative?

I downloaded it in, I knew nothing about the Savitzky-Golay theorem, I tried to search the famous thesis "Smoothing and Differentiation of Data by Simplified Least Squares Procedures" using google but couldn't find any.
Who can send me one and explain the vi detailedly??

Hi Xuelang

The code you have attached is not mine, it belongs to Serge Liberman

My code is based on the work of Peter Gorry, for details of the algorithms see the following paper.

General Least-Squares Smoothing and Differentiation of Nonuniformly Spaced Data by the Convolution Method

Gorry, P. A. Anal. Chem. 1991, 63, 534-539.

Throughout my code there are references to equations detailed in the above paper, so if you obtain the paper you should be able to follow the code.

Hi Xuelang

I don't have the paper in electronic form, however the journal is a very prominent one so your closest University ought to have it.
