This applet is designed to automate the routine calculations inherent in Gaussian
elimination. To use the applet, enter in the matrix coefficients (if you have
fewer rows and columns than displayed, just keep those extra rows and columns equal
to zero). Then use the five buttons on the left to manipulate your matrix, after
setting the options correctly of course. For instance, to swap rows 1 and 2,
change the second "Row 1" to "Row 2", and then press the "Swap" button.
