HyperSpec

What is it?

HyperSpec is a collection of Matlab® scripts/modules for derivative spectral analysis (DSA). I developed HyperSpec in the early 1990s while working on my master thesis in Cornell University. After more than a decade, I am surprised that people are still interested in using this software. Therefore, this page is created for interested users.

Before you proceed...

A few things need to be clarified before we proceed to the downloading phase.

First of all, HyperSpec was a graduate student's work, so do not expect it to be anything like those fancy commercial software you have accustomed to.
It was written in a very old version of Matlab (v 3.x) and has not been updated ever since. Last time I heard, other than a lot of annoying but (hopefully) harmless warnings and UIs popping up at wrong places, it still works in newer Matlab environments.
Currently, I don't have time or resources to maintain this software, so no feature requests or other updates will be answered in the near future.
Although I am confident of HyperSpec and none of existing users have reported any significant bug, it is provided AS IS and comes with absolutely NO WARRANTY whatsoever. Download and use it at your own risk.
Finally, only academic use is allowed with HyperSpec unless explicitly authorized by the author (i.e. me).

OK. I hope that is scary enough to let you turn away :-). However, if you still want to try it. Go ahead and download it. And please read on for a brief user instruction.

How to use it?

Unpack the archive. You'll get a HyperSpec folder with a bunch of M-files and a spc sub-folder in it.
Fire up Matlab. Change your Matlab workspace to the HyperSpec folder or append it to your Matlab path.
The top level script is called "HyperSpec.m". Load and run it under your Matlab prompt and here you go.

You need to prepare your spectral data in a spreadsheet (matrix) format. The first column is the wavelength and with each of the rest columns representing a curve (spectrum). Take a look at any of the .spc file inside the spc folder and you'll know what I mean.
