D Question 4 10 pts For the Octave function developed during lab that implements the method of successive over-relaxation (SOR), the output of the function was given as: [z, residual, iterative convergence, number of iterations] Given this, what does the residual variable represent? O A vector of residual values obtained by calculating the residual vector (R) # O A vector of solutions for the system of linear equations obtained after the last iteration, O A vector of residual norms obtained by calculating the Lo norm over the residual vector (R)= [A] (a) (b) over every iteration. O The number of iterations left for convergence. [A] {z}-{b} over every iteration.
