comment How to use the bisection method to solve $Ax=b$
in theory could you apply the bisection method multiple times in this case three, since three equations are being represented by $A$ and $b$ @abel

How would you find L and U? does one get the diagonal and the other doesn't?

comment How to convert Gauss-Siedel method to Successive Over Relaxation method.
So before the second iteration xOld is set to $x^{\omega}$ ?

comment How to convert Gauss-Siedel method to Successive Over Relaxation method.
A very thorough example. I was going with the first method you have mentioned here, however I think the second method $$x^{(\omega)}=(1-\omega)x^{(old)}+\omega x^{(new)}$$ was more what I was actually looking for. When taking the xold and xnew from the first iteration of gauss siedel to get $x^{(\omega)}$ Do you use $x^{(\omega)}$ for xold in the second iteration? @KittyL
