4 Consider N N Matrix 6 Main Diagonal 1 Two Diagonals Main Diagonal Example Matrix N 5 611 Q37124364

4. Consider the n × n matrix with 6 on the main diagonal, and 1 on the two diagonals above and below the main diagonal. For example, the matrix for n 5 is 61100 1611 0 A 1611 0116 1 00116 (a) Use matlab to apply six iterations of the Gauss-Seidel method to when 200 and all the components of b are 1. Start with the initial estimate 5 marks (b)
