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:
