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:
