This is starting to look more and more like a physical set of voltages.
Each iteration changes the values in the matrix less and less as the
solution asymptotically converges to the physical solution. In fact,
this iteration process could continue indefinitely. We must have a
stopping criterion, which is basically a test to detect whether
or not we've reached the right answer. The simplest stopping
criteria are based on the maximum changes in voltages from iteration to
iteration. If the values in the matrix are changing very slightly,
we have likely reached the solution. |
