The aim of this page is to provide some help with the installation of Octave.
First, you should download Octave from the Internet. Even though there are many sites from which you can download the software, a good one is:
http://easynews.dl.sourceforge.net/sourceforge/octave/octave-2.1.73-1-inst.exe
If you open that link, a window will appear offering you to Run or Save Octave. If you select Run, installation will begin immediately. If you select Save, you can install it later.
Note: if when you click on that link, your browser opens a website that asks you to select a mirror, try typing directly that address in the Address Bar of your browser.
I hope it helps. Good luck!!
