是Grey Method的使用方法，方便好用，欢迎大家下载，如果有问题，也欢迎给我留言，我的QQ号码是：55101(Gray Method is the way to use of convenient and you are welcome to download, if there are problems, I also welcome to voice mail, my QQ number is : 55101)

将状态矢量转换成轨道根数的Matlab源程序，输入是位置速度矢量，输出是轨道根数，有详细的注解(Convert the state vector of the orbital elements of the Matlab source code, enter the location of the velocity vector, the output of the orbital elements, with detailed comments)

first-order Engquist-Majda ABC in an FDTD program for 2D-TMz Wave.

M-file for simulating a QPSK transmitter by modulating with a pseudo random bit stream. A serial to parallel conversion of the pseudo random bit stream is performed with mapping of two bits per symbol. A cosine and sine carrier is configured and the I and Q symbols modulate these carriers. The I and Q carriers are combined and time and frequency domain plots are provided showing key waveforms at various positions in the QPSK transmitter.
