这是pi_4_DQPSK的MATLAB仿真源程序，很好的仿真了这种数字调制和解调(This is pi_4_DQPSK the MATLAB simulation of source, a good simulation of this kind of digital modulation and demodulation)

基于matlab的数字频带通信系统仿真，实现对采样信号的均匀量化(To achieve uniformity of the sampling signal quantification)

自己写的用Matlab模拟一个缓冲区大小（包括正在服务的那个）为10的随机排队系统。 （1）到达过程是的泊松过程（到达速率为Mu），服务时间服从独立指数分布（均值为1/Lamda）。 对Mu//Lamda=0.2，Mu//Lamda=0.8和Mu//Lamda=1.1三种情况进行仿真，求出队列中接受服务用户为n的概率P(n), n=0,...,10。并与理论结果进行比较。 （2）假设到达过程为均匀过程（到达速率为Mu），服务时间服从独立瑞利分布（均值为1/Lamda）。(yourself writing a simulation using Matlab buffer size (including services that are) for the following 10 Machine queuing system. (1) arrival process is the Poisson process (arrival rate of Mu), submit to independent service index distribution (mean of 1/Lamda). Right Mu// Lamda = 0.2, Mu// Lamda = 0.8 and the Mu// = 1.1 Lamda three of the simulation, Queue calculated users receive services n the probability P (n), n = 0 ,..., 10. And with the theoretical results. (2) It is assumed that the arrival process for the uniform process (arrival rate of Mu), submit to independent service Rayleigh distribution (mean of 1/Lamda).)

生成纵横向四阶方程，计算特征根，传递函数等，给出波特图及尼科尔斯图。( SURVEY is set up to make calculations based on the 12 x 12 Fmodel and 12 x 7 Gmodel produced by FLIGHT, with the generic business jet model trimmed for flight at V = 102 m/s and h = 3,050 m. The flags are set to generate a fourth-order, body-axis, lateral-directional model the data set to calculate eigenvalues, eigenvectors, and the transfer function aileron to roll rate and to show the Bode plot, Nyquist plot, and Nichols chart for the transfer function.)

说明：  利用MATLAB绘制均匀线列阵和均匀圆阵的方向图(Uniform linear array mapping using MATLAB and the uniform circular array pattern)

this code described the multi-ellipse for LMS method from noisy image

一个二维静电场，电位函数为φ（x, y），将正方形分成25个正方形网格。有16个内部网格点。假定16个网格点的初值都定为零，试用超松弛法确定16个内部网格点的电位值。(A two dimensional electrostatic field, the potential function for phi (x, y), the square into 25 square grid. There are 16 internal grid point. Assume that 16 mesh point of initial value at zero, trial overrelaxation method to determine the potential value of 16 internal grid point.)
