Editing Iterative method (section)

====Examples====

Basic examples of stationary iterative methods use a splitting of the matrix <math> A </math> such as
:<math>
  A = D+L+U\,,\quad D := \text{diag}( (a_{ii})_i)
</math>
where <math> D </math> is only the diagonal part of <math> A </math>, and <math> L </math> is the strict lower [[Triangular matrix|triangular part]] of <math> A </math>.
Respectively, <math> U </math> is the strict upper triangular part of <math> A </math>.
* [[Modified Richardson iteration|Richardson method]]: <math> M:=\frac{1}{\omega} I \quad (\omega \neq 0) </math>
* [[Jacobi method]]: <math> M:=D </math>
* [[Jacobi method#Weighted Jacobi method|Damped Jacobi method]]: <math> M:=\frac{1}{\omega}D \quad (\omega \neq 0) </math>
* [[Gauss–Seidel method]]: <math> M:=D+L </math>
* [[Successive over-relaxation|Successive over-relaxation method]] (SOR): <math> M:=\frac{1}{\omega}D+L \quad (\omega \neq 0) </math>
* [[Symmetric successive over-relaxation]] (SSOR): <math> M := \frac{1}{\omega (2-\omega)} (D+\omega L) D^{-1} (D+\omega U) 
\quad (\omega \not 
\in \{0,2\}) </math>
Linear stationary iterative methods are also called [[Relaxation (iterative method)|relaxation methods]].
