SEATWORK USING MATLAB

Create script file matlab that will solve the system of linear equation:

$x+4y-z=-5$

$x+y-6z=-12$

$3x-y-z=4$

using:

Gauss Seidel method

show the values of $x,y$ and $z$ in $4$ decimal places

show that the values obtained are the solution of the system. Do the checking in Matlab.
