一般无迹变换在轨迹跟踪中的仿真，有各种误差分析。(simulation of General UKF in trajectory tracking, there are a variety of error analysis)

KNN分类方法的MATLAB代码，可以用于数据挖掘中的K最邻近值聚类方法的实现(KNN classification of MATLAB code )

EKF的纯净程序，没有夹杂其他信息，本人经过测试，可以放心使用(EKF pure process, not mixed with other information, I tested, safe to use)

PWE（平面波展开法）计算二维固-固圆柱形声子晶体的XY模式。(PWE (plane wave expansion method) to calculate the two-dimensional solid- XY mode phonon solid cylindrical crystals.)

直接序列扩频系统（DS，Direct Sequence）又称为直接序列调制系统或伪噪声系统（PN 系统），简称为直扩系统，是目前应用较为广泛的一种扩展频谱系统。要传送的信息经伪随机序列编码后对载波进行调制。在发信端越冬用扩频序列去扩展信号的频谱，在收信端，用相同的扩频友序列进行解扩，将展宽的频谱扩展信号还原成原始信号。因为伪随机序列的速率远大于要传送信息的速率，所以受调信号的频谱宽度将远大于要传送信息的频谱宽度，帮称之为扩频(Direct sequence spread spectrum (DS, Direct Sequence) modulation system, also known as direct sequence or pseudo-noise system (PN system), referred to as direct expansion systems, is currently the more widely used as a spread spectrum system. To send the information encoded by the pseudo-random sequence of carrier modulation. End of winter in the letter to extend the signal with the spreading sequence of spectrum, in the end prepared to receive and use the same sequence spread spectrum despreading friends, broadening the spectrum to restore the original signal expansion signals. Because the rate of pseudo-random sequence is much larger than the rate of information to be sent, so the frequency spectrum by adjusting the width of the spectrum is much larger than the width of the information to be sent to help is called spread spectrum)

说明：  利用MATLAB可以产生各种形式的随机数，进行随机解决一些实际问题（系统的寿命、重积分、预测公司经营）(using MATLAB can produce various forms of random numbers, random solve some practical problems (system of life, re-integration, the company forecast operating))
