To see the details of the solution vector, if needed, press the

@EDIT! button.

This will activate the Matrix Writer. Within this environment, use the right-
and left-arrow keys to move about the vector, e.g.,


Thus, the solution is

x = [15.373, 2.4626, 9.6268].


To return to the numerical solver environment, press

`.


The procedure that we describe next can be used to copy the matrix A and
the solution vector X into the stack. To check that the solution is correct, try
the following:

• Press ——, to highlight the A: field.
• Press L @CALC@ `, to copy matrix A onto the stack.
• Press @@@OK@@@ to return to the numerical solver environment.
• Press ˜ ˜@CALC@ `, to copy solution vector X onto the stack.
• Press @@@OK@@@ to return to the numerical solver environment.
• Press ` to return to the stack.


In ALG mode, the stack will now look like this:
