说明：  这是一个关于卡尔曼滤波的学习资料，可以帮助初学者学习该滤波算法(This is a study on the Kalman filter information that can help beginners learn the filtering algorithm)

这是一个模拟第3类模式地震波的matlab脚本。 This a collection of Matlab scripts that solve the antiplane (mode III) earthquake dynamic problem with slip-weakening friction, on a 1D fault embedded in a 2D homogeneous elastic unbounded medium. The problem is formulated as a boundary integral equation and the elastodynamic kernels are analytically derived in the spectral domain (spatial wavenumber). The method is explained e.g. by Morrysey and Geubelle (1997), and has been improved and extensively used by Nadia Lapusta, Alain Cochard, etc. (This is a Class 3 model simulation of seismic waves of matlab scripts.

MFCC,即倒谱系数，也是语音的一个特征之一，能够充分利用人耳的特性 ％ 具体的求法就是预处理，然后加窗，进行傅立叶变换，再求出功率普 ％ 然后得出其自然对数，最后进行dct变换 ％ 代码是用matlab写的，用到的一个语音工具箱，可以从网络上下载。(MFCC, that is, just a few pedigree, as well as a voice of one, to take full advantage of people's ears% of the specific characteristics of the solution is pretreatment, then increasing the window, Fourier transform, another sought power pu% then come to its natural logarithm, culminating transform% Extra code is written in Matlab. use of a voice box can be downloaded from the Internet.)

matlab实现语言信号的加窗分帧 短时能量等特征值的提取(matlab implementation language framing windowed signal characteristics such as short-term value of energy extraction)

matlab仿真，适合3/4、2/3、5/6、1/2，速率的打孔程序(matlab simulation, for 3/4, 2/3, 5/6, 1/2, the rate of drilling procedure)

ofdm正交频分复用中六种时间同步算法,时间同步很重要。(ofdm the six time synchronization algorithm ofdm of six time synchronization algorithm)

用matlab语言 分别判断出三个圆的圆心，并且求出这三个圆之间的距离(Matlab language were used to determine three of the center circle, and obtained the three round distance between)

有用的动态目标跟踪例程，值得参考！！留着说不定有用(Useful dynamic target tracking routines, it is also useful! ! Retention maybe useful)
