Nice interactive matrix inverse calculator
Nice interactive matrix inverse calculator. User enters elementary row operations and views their effect. All the steps are recorded by the applet and displayed for the user to review. The applet generates new matrices to invert at the push of a button. The operations use only rational numbers. The user cannot enter a matrix to invert.
Nice, but students cannot enter their own problem
Easy to use and enter data for row operations. Students cannot enter their own problem. There is a"glitch"; the list of operations is not cleared when a new problem is initiated.
nicer interface than other applet I looked at; no glitch for me
This is a nice applet for calcualting the inverse by applying row operations to an augmented matrix. This has a nicer interface than the other applet I looked at for calculating inverses. It also provides a nice bullet list of facts about inverses.The 'glitch" did not occur on my computer.
