Yesterday, it was snowing. Today it is not. I like it better when it is snowing.

In engineering class, we use a certain mathematics program, MATLAB. It is rather expensive to buy, something like two hundred dollars is my understanding.

There is a free program that is very similar, Octave, that I stumbled upon while browsing the Internet. It is very nice. Installing it is a little tricky though. Here, I'll tell you how to install it on a Mac.

  1. Download the disk image.
  2. Double click on the .zip file in the Downloads folder.
  3. Click on the .dmg file.
  4. Drag Octave.app from the new virtual disk to the Applications folder.
  5. In the Extras folder of the disk, click on the .dmg file there.
  6. From the new disk, drag GNU Plot to the applications folder.

Congratulations! You have installed Octave on your Mac. To run it, double click on the octave icon in the Applications folder. Have fun with those matrices! Mmm … yeah!
