Pseudo velocity shock data analysis calculations using octave

Abstract

Octave [1] is a GNU licensed free signal processing program that does all our basic shock data calculations and plotting. It's more clumsy than Matlab [2], but it's free. I have adjusted my Matlab programs to run on it, and have enough done for a paper on how to do it. The paper will give you a big start in doing shock data analysis on your own. I've always felt less than helpful giving papers on how to do shock analyses, knowing that the user needs a two thousand dollar program to use the material. This changes the game entirely. This paper shows how to use Octave to do all the basic shock data analysis calculations and plotting. Once you can do analysis for yourself, you gain understanding of data analysis. It will give you a start and enough confidence to see that you can learn it. I will give out my programs, which you can use as is, or change to better suit your needs. © The Society for Experimental Mechanics, Inc. 2013.
