Accessing Octave


Octave is developed by the GNU Project for the GNU operating system, which is most often paired with a Linux kernel. At its core, Octave is therefore GNU/Linux software. It runs natively on GNU/Linux machines. It must be ported (converted somehow) to run on other operating systems like Windows or macOS. Ports (converted programs) exist for these operating systems, but are sometimes more complicated to install or older than the most recent version.

See the GNU Octave page for the latest information on installing Octave. The wiki pages referenced there have very detailed advice.


The source for this project includes LyX, Octave, GeoGebra, wxMaxima, xfig, text, and graphics files. Here are several ways you can get the source.

Minimally, you will need a LyX installation to view and edit the textbook source files. Other tools are required to view and edit the diagram source files. Besides the software highlighted above, GIMP and the command line utilities pdfcrop and pdfseparate were used in the creation of the text.

As are the textbook and Octave, all the tools used to create this textbook are open source projects. You may download and use them free of charge, and even study and modify their source code if you wish.

Who uses Tea Time Numerical Analysis?

Tea Time Numerical Analysis was specifically designed for use at Southern Connecticut State University but with a mind to make it more generally useful. If you are using it elsewhere or know of someone who is, please drop me a note.
