Gaussian Eliminator Tool

For Those Who Hate Doing Arithmetic By Hand


Below is a java applet that can be used to solve linear equations.

Edit the two text fields to specify the number of rows and columns you want and then click on the Go Eliminating button.

A new window will pop up with an empty matrix having the correct dimensions. You can enter data elements into each text field to define a specific problem. Alternatively, you can click on Generate Random Problem to get a random problem to play with.

To normalize a row, simply click on the variable-button situated on the diagonal for the row that you want to normalize. To make a nondiagonal element zero, click on the variable-button to the right of that element. To swap rows, click on the two rows you want to swap in the Swap column.

Coefficients on the diagonal are highlighted in pink.
