Hi
I have written a 3D FDTD sample code by matlab based on Sulivan book.
ABC used for these codes is PML with 7 cells.

great work!

why don't use the following string:
dx(1:Imax,2:Jmax,2:Kmax) = dx(1:Imax,2:Jmax,2:Kmax) + 0.5*(hz(1:Imax,2:Jmax,2:Kmax) - hz(1:Imax,1:Jmax-1,2:Kmax) - hy(1:Imax,2:Jmax,2:Kmax) + hy(1:Imax,2:Jmax,1:Kmax-1));

instead of:
for k = 2:Kmax
for j = 2:Jmax
for i = 1:Imax
dx(i,j,k) = dx(i,j,k) + 0.5*(hz(i,j,k) - hz(i,j-1,k) - hy(i,j,k) + hy(i,j,k-1));
end
end
end

it is faster!

If you post what you believe are the essential parts of your program which do not work properly somebody may be able to help you.
