盲源分离代码matlab程序，实现将信号源分离(Blind Source Separation code matlab program to achieve the signal source separation)

相图与庞加莱截面，但程序有点问题，需要交流，相图应该是对的(A problem, the phase diagram and Poincare section)

ekf_algorithm for Mobile Robot Localization

Matlab程序，GUI窗口 用FFT程序计算有限长度正弦信号y=sin(2*pi*f*t) ,0<=t<=N*T(FFT program calculate the finite length of the sinusoidal signal y = sin (2* pi* f* t), 0 < = t < = N* T respectively the DFT results obtained and analyzed and discussed in the following cases: a) the signal frequency f = 50Hz, the sampling the credited with N = 32, the sampling interval T = 0.000625sb) signal frequency f = 50Hz, the sampling points of N = 32, the sampling interval T = 0.005sc), the signal frequency f = 50 Hz, the sampling points N = 32, the sampling interval T = 0.0046875sd) signal frequency f = 50Hz, the sampling points of N = 32, the sampled interval T = 0.004se) signal frequency f = 50Hz, the sampling points of N = 64, the sampling interval the T = 0.000625sf) signal frequency f = 250Hz, the sampling points N = 32, the sampling interval T = 0.005sg) c) a signal-post 32, to do a 64-point FFT)

关于bpsk调制和解调，进行模拟调制，自行编写绝对正确(About bpsk modulation and demodulation, to simulate modulation, self-preparation is absolutely right)

说明：  最速下降梯度法matlab程序和用拟牛顿法求极小值点(apply a gradient–descent based error minimization approach to minimize the difference between the real deformation and the simulated one given the elasticity parameters)

matlab编写的串口调试工具，数据接收部分采用中断方式，保证了实时的数据显示 。在获取端口部分采用了try catch 的方式，可以更加方便的选取端口。(this is a simple serial tool scripted by matlab. I used interrupt to ensure the instant display of received data.)

利用Matlab产生各种回声、击掌等特殊效果的音频程序。(Matlab, generate a variety of echo, clap audio programs and other special effects.)
