<数字信号处理>（胡广书 编）课后习题的matlab编程(lt; Digital signal processing gt; (Hu-book series) Exercise of Matlab after-school programming)

课程设计，关于数字信号处理的课程设计，中南大学的(Curriculum design, course on the design of digital signal processing, Central South University)

overall snr estimation in signal

在Matlab环境下，仿真实现了INS导航，输出量为经度、纬度、北东天三个方向以及航向、俯滚、偏航随时间的变化。(In Matlab, Simulation of the INS navigation output for the longitude, latitude, North East, the direction and course of three days, overlooking the roll, yaw over time.)

阵列天线多端口的馈电操作。在进行波束赋形或相控阵天线设计时，若天线端口数量巨大，可以用该程序一次实现对所有天线端口相位及赋值的输入。(Multi-array antenna feed port operations. Performing beamforming or phased array antenna design, if the huge number of antenna ports can be used to implement the program once all the input phase and the antenna port assignment.)

信息论法信号源数估计，包扩性能比较，和分析(Source of information theory method was estimated, including the expansion of performance comparison, and analysis)

基于MATLAB程序的LMS算法程序及一个例子(Based on the the MATLAB program' s LMS algorithm and an example)

Crout s algorithm is used when the inversion of large matrices, say 1000X1000 is difficult. So Crout s algorithm uses LU decomposition method to get the same results as the inversion of Matrix.

-u"+u^2=x, 0<x<1 u(0)=0, u(1)=0

In order to model the chaotic motion of the double pendulum,i am going to use Matlab solving the problem using numerical methods such as Rung-Kutta and Ordinary Differential Equations (ODE).
