five point scheme as an example, the new values on the nodes are the
average of the initial values of the adjacent four points. After the new
value is calculated, the old value is retained to calculate the new value
of other points. This kind of simple iteration converges very slowly and
is rarely used now. However, if it is improved slightly, the old value will
