2维FDTD的MATLAB代码，TM波代码-2 dimension FDTD program (TM mode)

All boundaries are perfect conductors.

// For Visualization of the field, I use PGPLOT which is available as port

// (for FreeBSD) or binary package (for Debian Linux).

//　(1) In FreeBSD, compile with

//　gcc-o fdtd fdtd.c-I/usr/local/include-L/usr/local/lib-L/usr/X11R6/lib

// -lcpgplot-lpgplot-lg2c-lX11-lm

//　(2) In debian Linux, complile with

//　gcc-o fdtd fdtd.c-lcpgplot-lpgplot-L/usr/X11R6/lib-lX11-lpng

// -lz-lm
