Consider the system 1. Use any direct method (i.e., analytic method) you know to solve for x,y and z. 2. For the Iterative methods, you may use Excel or Matlab. Solve the system (as is) using Gauss-Seidel with initial solution of (x, y, z) = (1,0,1). Answer: Iteration 1,% a% a. 1 2 S 4 5 Iteration 3x + 7y + 13z = 76 x + 5y + 3z = 28 12x + 3y - 5z = 1 1 2 S 4 5 b. Solve the system (as is) using Gauss-Jacobi with initial solution of (x, y, z) = (1,0,1). Answer: X y al% y Z a% als% Z a% Observations: Write your observations from the results in (a) and (b). c.
