极化SARlee滤波程序，对极化相干矩阵进行处理，也可以调整为普通图像(SARlee polarization filtering procedures to deal with polarization coherent matrix can also be adjusted to the general image)

主成分分析的matlab编码,用于矩阵求特征值特征向量(Principal component analysis matlab coding for matrix eigenvalue eigenvector)

源于谱分析的交通流预测，预测效果相当不错(From spectral analysis of traffic flow forecasting, prediction is quite good)

ofdm调制的matlab程序实现，经过验证是可以实现的，但是具体应用的时候需要自行修改程序中的一些参数(ofdm modulation matlab program, after verification can be achieved, but it requires its own specific application to modify some of the parameters in the program)

This Program simulates the MVDR beamformer which is useful for beginners.

说明：  用于方程求根的二分法。方程求根。二分法。(Dichotomy method to solve the functions.)

该程序用于求解时间延迟t和嵌入维数m，该方法不同于自相关函数法和gp法，可以同时求解出两个量t和m的值，非常方面，在求解lyapunov指数时经常用到该方法(The procedure used to solve the time delay t and the embedding dimension m, the method is different from the self-correlation function gp method can solve the two quantities t and the value of m, the very aspect, often used to solve the lyapunov exponentthe method )

SMI方向图和性能(波束形成算法，自己修改） 优点： 收敛速度快 缺点：1 当阵元输出含有较强的期望信时，或者期望信号与干扰信号相关时，性能急剧下降.2 由于权向量含有方向矢量，因此对阵列的幅相差非常敏感；3 ,期望信号的功率不能过大，比干扰信号相差几十dB，也就是说，在小期望信号、大干扰信号情况下，也可进行SMI处理。 (SMI pattern and performance (beamforming algorithm, make changes to) Advantages: fast convergence Disadvantages: 1 output when the array elements with strong expectations of the letter, or related to the desired signal and interference signals, the performance sharply .2 direction vector containing the weight vector, so the array is very sensitive to the amplitude difference 3, the desired signal The power can not be too large, than the difference between the scores of interference signal dB, that is, in the small desired signal, large signal interference case, SMI can also be handled. )

说明：  用于地震数据的拉冬变换,可以分离直达波，折射波河反射波(use to radon change)

matlab读取YUV视频数据参考程序，matlab实现(matlab read YUV video data reference program, matlab achieve)
