4. Consider the matrix equation Ax = b where, A = a b 1 1 where a, b > 0. (a) When is A strictly diagonally dominant and what does this tell us about the Gauss- Seidel method for Ax = b. (b) Find the iteration matrix for the Gauss-Seidel method applied to Ax = b. (c) Using your previous answers, for what values of a and b does the Gauss-Seidel method converge.
