This system has the same number of equations as of unknowns, and will be

referred to as a square system. In general, there should be a unique solution to

the system. The solution will be the point of intersection of the three planes in

the coordinate system (x

) represented by the three equations.

To enter matrix A you can activate the Matrix Writer while the A: field is

selected. The following screen shows the Matrix Writer used for entering matrix

A, as well as the input form for the numerical solver after entering matrix A

(press ` in the Matrix Writer):

Press ˜ to select the B: field. The vector b can be entered as a row vector

with a single set of brackets, i.e., [13,-13,-6] @@@OK@@@ .

After entering matrix A and vector b, and with the X: field highlighted, we can

press @SOLVE! to attempt a solution to this system of equations:

A solution was found as shown next.

To see the solution in the stack press `. The solution is x = [1,2,-1].
