• Tarball of the whole works!
• Documentation (pdf)
• Direct Helmholtz solver: helmholtz.m
• Intergrid Transfers: ctof.m , ftoc.m and a way to test them intergrid_test.m
• Damped Jacobi smoother: dampj.m and a test for that smoother: jacobi_image.m
• Test for correct solution and timings: time_test.m
• A pair of two-grid codes and the test codes: twogrid.m , twogrid_test.m , twog.m , twogrid_testa.m
• Three ways to do a v-cycle and test it: vcycle1.m , vcycle2.m , vcycle.m , vcycle_test.m , vcycle_testa.m
• Three flavors of FMG: fmg.m , fmg1.m , fmg2.m , which you test with time_test.m
