Gauss seidel

Solution of system of equation by Gauss seidel

Example : Solve using Gauss Seidelmethod:

10x1 -x2+ 2x3 = 6

-x1 + 11x2 - x3 +3x4 = 25

2x1 - x2+ 10x3 -x4 = -11

3x2 - x3 + 8x4 = 15

Enter matrix A : [10 -1 2 0;-1 11 -1 3; 2 -1 10 -1;0 3 -1 8]

Enter matrix B : [6 25 -11 15]'

Enter initial guess : [0 0 0 0]'

Enter tolerable error : 0.001

Enter no of iteration : 10

Solution after 10 iteration is:
