研究Chen系统的混沌运动，通过理论分析与数值计算分析系统基本动力学性质，并通过系统相图、全局分 岔图与Lyapunov指数图分析该Chen混沌系统动力学行为．(Chen chaotic motion of the system, through theoretical analysis and numerical calculation and analysis system of basic dynamic properties and phase diagram of the system, the global bifurcation diagram and Lyapunov exponent analysis of the Chen chaotic system dynamics.)

文利用带噪语音经特征基函数矩阵转换后所具有的稀疏特性，用最大似然估计方法对转换后得到的稀疏 分量进行非线性压缩去噪，然后再经过反变换和重构恢复出原始语音信号的估计。特征基函数矩阵反映了语音数据本 身的统计特性，因此具有很好的合理性和可取性。仿真结果表明利用稀疏编码方法能极大程度地抑制背景噪卢，与小波消噪法相比优势明显。(a speech enhancement algorithm based Compressed Sensing.)

相关函数表示两个或同一个时间序列之间在任意两个不同的时刻取值之间的相关程度。相关程度越大,相关函数值就越大。用MATLAB对上述相位测量方法进行仿真,考察序列长度和噪声的相关性对测量结果的影响。

说明：  国外模式识别课上老师给的pca和lle代码(These codes are given by the teacher in the pattern recognition class)

说明：  相关向量机RVM.可以做分类，回归。具体运行例子，演示程序在Demo.m，供大家参考和修改成自己想要实现的程序。(Can do classification and regression. Specific operation examples. Put it in a WORD specifically for your reference and modification into the program you want to achieve.)

只是偶搭建的关于二级倒立摆模糊控制的Matlab模块文件，可以直接用，肯定对研究倒立摆的同仁有帮助(Only occasionally set up on a double inverted pendulum fuzzy control module of the Matlab files, can be directly used, the study affirmed the inverted pendulum has Tongren help)

说明：  pso粒子群算法的matlab程序.实现了第一个函数的优化.其他函数类似.比较简单明了(PSO PSO algorithm Matlab procedures. The first realization of a function optimization. Other similar function . relatively simple to understand)

in this program, the sparse representation of data was calculated.
