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?
