此书包含了MATLAB的所有命令，对学习MATLAB的学者很有帮助，也可作为一本工具书。(This book contains all the MATLAB commands, useful for learning MATLAB scholars, but also can be used as a tool.)

构造一个空的双向栈，判断双向栈是否存在，出栈，入栈，判栈空，将栈置空，判栈满，取栈顶(Construct an empty two-way stack to determine whether there is a two-way stack, out of stack, stack, sub-stack empty, set the stack is empty, sub-stack is full, take the stack)

Fit a multivariate gaussian mixture by a cross-entropy method. Cross-Entropy is a powerfull tool to achieve stochastic multi-extremum optimization.

RS分形算法matlab代码实现,既利用RS方法计算时间序列的分形hurst指数(RS fractal algorithm matlab code, we use RS calculated time series fractal Hurst index)

OFDM仿真，包括详细的解析，对初学者有很好的作用(OFDM simulation, including detailed analysis of the beginners have a good role)

this file can be used to calculate the entropy of english language.

扩展卡尔曼与粒子滤波结合的程序,用扩展卡尔曼作为提议分布，然后利用粒子滤波进行滤波跟踪，效果比常用的粒子滤波要好！均方根误差也比较小。(Extended Kalman particle filter in conjunction with a program, as proposed by the extended Kalman distribution and particle filter for filtering track, the effect is better than the commonly used particle filter! RMS error is relatively small.)

matlab实现希尔伯特黄变换程序，包含emd分解和HT变换(Matlab implementation of the Yellow Hilbert transform procedures, including EMD decomposition and HT transform)

EMD或者LMD的能量密度与其平均周期的乘积K值，当K值发生较大变化的时候，证实该分量为白噪声，可以剔除，将剩下的分量进行重构，达到去噪的目的。(The product of K EMD or LMD energy density and average cycle value when the K value was changed greatly, the component for white noise can be eliminated, the remaining components are reconstructed to achieve the purpose of de-noising.)

采用二阶盲源分离程序编写的模态参数识别Matlab工具箱。(Toolbox for performing modal dentification using second order blind source separation methods)
