Installing Octave in Linux

Most Linux versions include a package management system, and Octave is a very common tool. Here as some of the ways to install it

Fedora: sudo yum -y install octave

Ubuntu: sudo apt-get install octave

The signal processing toolbox is already auto-enabled, so you can test installation with:

x = randn(1, 101);
plot(x);

Now to test if the signal processing toolbox is installed

x = randn(1, 101);
[y, shifts] = xcorr(x);
plot(shifts, y, 'r.:');
