Octave install packages

On http://octave.sourceforge.net/packages.html you can find all packages for Octave.
You can download all packages in a single file or you can take the ones you want.
After downloading the package install it by typing pkg install <packagename and path> like pkg install signal-1.0.7.tar.gz.

Purdue University: ECE438 - Digital Signal Processing with Applications

• Matlab getting started

This document in the beginning has has two links to a basic and an advanced tutorial. I can't find them bu I think it is this document:

• Matlab: Charles Bouman's and Michael Zoltowski's Tutorial

• Short help on Parks-McClellan design of FIR Low Pass Filters using Matlab
• More files from ECE438

Free Software

GNU Octave

• Octave - Wikipedia
• Octave homepage
• Octave download

install the package signal-1.0.7.tar.gz to get resample.m and other signal processing functions
resample.m in the newest version does not work - get older version from subversion
audio-1.1.1.tar.gz doesn't work on Windows - use playrec instread
