MATLAB Implement the steepest descent method to solve Ax b. You can somewhat base your code on the Jacobi/Gauss-Seidel code and essentially just change the update rule (a) Iterate until the relative residual norm falls below a threshold that ensures the relative error to be less than a tolerance of 10-9. What is that threshold? MATLAB Implement the steepest descent method to solve Ax b.
