    Iterative refinement?

    Can anyone kindly explain to me how to carry out the iterative refinement technique on a system of linear equations?

    Thank you!

    6x1 + 7x2 + 8x3 = 21
    7x1 + 8x2 + 9x3 = 24
    8x1 + 9x2 + 9x3 = 26

    Re: Iterative refinement?

    i think there shall be a starting value of error e(0)=[e1,e2,e3]T or x(0)=[x1,x2,x3]T (T means Transpose) which help us to find residual. Than after many substitutionour iteration on x will converge to real solution

    What method are you supposed to use ?
    Jacobi ?
    Gauss-Seidel ?
    SOR ?
