The IterativeFormulaTutor command launches a tutor interface that takes the linear system  and an initial vector  and computes the matrix  and vector , of the equivalent system .

A Matrix and Vector Editors allow users to edit the matrix and vectors easily within the tutor.

All other available options are controlled in the tutor interface.

If A is not specified then IterativeFormulaTutor uses a default square matrix.

If b is not specified then IterativeFormulaTutor uses a default vector.

The iterative methods available in this tutor are:

There are two digit controls in the tutor.  The Digits option controls the number of digits kept during floating-point computations, and the digit precision option controls only the number of digits to which final results are rounded in the maplet display window. The digit precision option has no effect on the output returned from the maplet upon exit.
