Providing evidence of your approach in a spreadsheet or word document, carry out Point-Jacobi and Gauss-Seidel iterative approaches on the following set of equations: -1x1 + 1x2 + 7x3 + 1x4 - 2x5 = 3 2x1 + 1x2 -1x3- 2x4 +9x5 = 33 2x1 + 8x2 + 1x3- 2x4 + 1x5 = 17 1x₁-3x₂ + 1x3 + 10x4 + 2x5 = 56 6x1 + 1x2 - 1x3 + 1x4 - 1x5 = 20 Complete the following: Providing screenshots and commentary, carry out an investigation using both the Point-Jacobi and Gauss-Seidel iterative approaches using the given MATLAB code. Consider different tolerances (i.e., Tol = 0.1, 0.01 and 0.001. What are the implications of the variations in these values of tolerance? What is the error associated with each answer for the values of X1, X2, X3, X4, and for these variations in tolerance? Comment on the number of iterations required to achieve convergence in each instance. What conclusions can be drawn from this investigation?
