Q1 The linear system Ax = b is given by:
x1−x2 + 4x3 = 7
4x1 + 2x2 –x3= 18,
x1 + 3x2+ x3 = 16,
has the solution x=(3, 4,2)T. Using the initial guess x (0)=(1, 1,1)T
- Solve the above system as is using: Gauss-Seidel method. If the error increases, what does that mean and what should you do? (see b below)
- Condition the system so that convergence is secured and solve using the Gauss-Siedel method.
Q2: Find a system of linear algebraic equations Ax=b that needs pivoting and carry out the solution (using a limited number of significant digits, say 3) as Without pivoting, With partial pivoting, With total pivoting and Make conclusions.
