This some optimization to use MATLAB matrix notation. Others may find a way to further optimize the nested loops.
3D FDTD 計算程序
ToyFDTD1 is a stripped-down, minimalist, 3-dimensional FDTD code that is published under the GNU General Public License. It is the first in the ToyFDTD series of codes, and it illustrates in heavily commented C and Fortran the basic tasks in implementing a simple 3D FDTD simulation.
