Gauss seidel method of convergence

  1. Feb 11, 2010 #1
    hi,

    im trying to calculate the spectral radius (gauss seidel method) to test whether or not its converges. i no that if the modulus is less than one it converges. however, my answer gives a mixture of solutions which are above and below one - 0.45 and 2.15 and 0. so is this divergent or convergent? does all three need to be below 1 in order for it to converge?

    thanks

    I can't make heads or tails of your question, but the spectral radius is one number only.
