There's only one example, and the interface is not perfect
Java applet gives example of the calculation of a matrix inverse. Gives students a chance to invert a matrix without making arithmetic errors. There's only one example, and the interface is not perfect, but with a little experimentation, it's not hard to use. The last row operation has a "Do it" button, but the other operations are implemented by pushing the other rounded rectangle buttons, not the "Do It" buttion.
Convenient applet for calculating inverse
Convenient applet for calculating inverse by applying row operations to an augmented matrix.
