说明：  一类基于奇异值分解的Lyapunov指数计算方法

主要讲解一些关于matlab的指令 方便大家在使用的时候查找(Explain some of the main directives regarding matlab convenient time for everyone in the use of search)

涵盖了MATLAB多种常用的数学函数，包括：基本数学函数，MATLAB常用的三角函数，MATLAB的永久常数，MATLAB基本绘图函数等。(Covers a variety of commonly used MATLAB mathematical functions, including: basic mathematical functions, MATLAB used the trigonometric functions, MATLAB permanent constant, MATLAB and other basic drawing functions.)

釆用一个二阶系统的模型代替真实系统，其差分方程表达式为： 将此系统在计算机上仿真，输入信号u(k) 是幅值为1 的PRBS 信号，噪声e(k) 是（0，1）的正态分布序列，它的方差是可以调整的。这个系统的输出釆样值z (k) 与u (k) 作为已知数据，采用最小二乘法估计这个系统的参数。 (Preclude the use of a second-order system model instead of the real system, the differential equation expression: this system on a computer simulation, the input signal u (k) is the amplitude of the PRBS signal, and the noise e (k) (0 , 1) the normal distribution of sequence, its variance can be adjusted. The output of this system the Bian samples z (k) and u (k) as known data, the method of least squares to estimate the parameters of this system.)

DDS用matlab实现的源程序，可以实现调频信号，和调相信号(DDS source code with matlab implementation, can achieve FM signal, and phase modulation signal)

说明：  识别五官的matlab代码,对五官进行框选。(a matlab code on solving face-recognization)

说明：  基于模型预测控制算法研究自动驾驶车辆轨迹跟踪(Trajectory tracking of autonomous vehicle based on model predictive control algorithm)

一个音符起点检测程序，其中使用了非负矩阵分解以提取特征减少运算量(NOTE ONSET DETECTION USING NMF)

对数据进行EMD分析时，如果数据不是纯的白噪声,则分析过程中一些尺度将会丢失,出现模态混叠现象。EEMD通过附加均匀分布 在整个时频空间的白噪声，可有效抑制这种现象的发生。(EEMD is insufficient for the EMD method, we propose a noise-assisted data analysis methods. EEMD decomposition principle is: when the additional white noise uniformly distributed throughout the time-frequency space, the time-frequency space is carved up by the filter component of the composition at different scales.-)
