- sor_test.m, calls all the tests;
- sor_test.sh, runs all the tests;
- sor_test.txt, the output file.

- sor_test01.m, tests the SOR iteration;
- sor_error.png a PNG image of the square of the norm of the residual (Ax-b).
- sor_evolution.png a PNG image of the evolution or trajectories of the solution values as the iteration proceeds.
- sor_motion.png a PNG image of the "motion" of the solution values, which is the averaged distance each entry moves during an iteration.
