3.7.6 Gauss helper

The Gauss helper augments a subject matrix with a column of row-selector buttons, a row of action buttons and an expression template with a Go button.

gaussɱ([(0, 0, 6, 18), (2, 10, -4, 4), (2/3, 4, 0, 6)], (, "?", -1, -1, 1))

The template expression changes as the row and action buttons are touched. The generated expression is applied by clicking on Go . Each time an expression is applied, the matrix is changed. The expressions conform to the Gaussian row operations.

As a term embedded in a larger expression, the value of the augmented matrix is the matrix itself. To remove the augmentation, use the button with the larger X: X .

More detail on the Gauss helper is given in §5
