11 Consider the matrix problem $ A x = b$, where $A = L + U + D$.
38 x^{1/2} = \omega (L + D)^{-1} b
41 x = (1 - \omega) x^{1/2} + \omega (U + D)^{-1}(b - L x^{1/2}) = x^{1/2} + \omega (U+D)^{-1}(b - A x…
86 x = \omega (L + D)^{-1}b
97 x = (L + D/\omega)^{-1}b

103 (L + D/\omega)^{-1} A (U + D/\omega)^{-1} y = (L + D/\omega)^{-1} b.
105 Then after this system is solved, $ x = (U + D/\omega)^{-1} y$. If an initial guess that is nonzero…
106 initial guess for $ y$ must be computed via $ y = (U + D/\omega) x$.
