使用ESPRIT方法来进行谐波频率的估计(using esprit method to estimate the frequence)

基于LSB的直接4bit替换法，就是直接用秘密图像像素值的高4bit去替换载体图像像素值的低4bit。 (Direct 4bit substitution, that is, the direct use of the secret image pixel values of the high-4bit image pixel value to replace the carrier' s low 4bit.)

应用牛顿-拉夫逊算法的潮流计算程序，其中几个函数的程序，自己在这里找(Application of the Newton- Raphson algorithm for the flow calculation procedures, the procedures for a few functions that they find here)

改程序主要是针对雷达信号处理中的应用，结合matlab处理(Reform program is mainly aimed at the application of radar signal processing, combined with matlab processing)

FRFT 具体的程序，有关天处理LFM信号的，特别好。(FRFT specific procedure, the days of LFM signal processing, particularly good.)

SMOOTH uses a vectorized implementation that may be slow when X and/or FRAME_LENGTH are very large. The number of elements that are used for calculation is length(X)*FRAME_LENGTH. The algorithm vectorizes the operation by creating a matrix of indexes and extracting its diagonals. E.g. for a vector of length 4 and frame_length of 2, the algorithm creates a temporary zero-padded matrix x2 from which it creates a set of indexes:

matlab粒子群程序，里面的bug请检查 (swarm)

是一个产生高斯脉冲的小程序，并且有调幅，有时延和频移，叠加了一定的高斯噪声(Is a produce gaussian pulse of small program, and have an am, time delay and frequency shift, superimposing a gaussian noise )

说明：  构建状态空间模型，运用模型预测控制控制追踪，适用于初学者(Construct a state space model, use model predictive control to control tracking, suitable for beginners)
