The Matrix
The assignment sheet for this project can be found here.
Basically, the objective is to create a program which allows manipulation of matrices, as in the mathematical structure. I spent 2 weeks working on making my implementation work.
At first I wrote it as an application, but for posting it to this website, I have converted it into an applet with some lost functionality (it cannot save or load matrices).
The source code for this can be found here.
