When doing black and white figures with several curves, it is sometimes difficult to uniquely identify each curve, since the number of different line styles is quite limited.

audio signal processing and recognition,是一本台湾张智星教授所写的关于语音处理的书籍，网上有另一个版本书名叫《audio processing》，和这个有点区别，两个结合看效果会更好！(audio signal processing and recognition, is a book written by Professor Zhang Zhixing Taiwan books on speech processing, there is another version of the online book called "audio processing", and this little difference, the two combined to see better results!)

小波包分析提取振动信号中的特征频率，包括 MUSIC算法，ESPRIT算法 ROOT-MUSIC算法，进行逐步线性回归。( Wavelet packet analysis to extract vibration signal characteristic frequency, Including the MUSIC algorithm, ESPRIT algorithm ROOT-MUSIC algorithm, Stepwise linear regression.)

单频估计kay算法的仿真源程序，系统为QPSK调制，信道为高斯白噪声信道。(Single frequency estimate kay algorithm simulation source code, the system is QPSK modulation, the channel is Gaussian white noise channel.)

激光谐振腔的稳定曲线,并通过颜色的标定显示来回反射的激光(the stability curve of Laser cavity ，and then show the route of the light through the cavity .)

This program performs the Duane growth method with least-squares fit of an input data set to a straight line

说明：  这是关于EMD法计算样本熵的程序，希望能给各位带来帮助。(This is about the EMD method to calculate the sample entropy program, I hope to help you.)

这是一个遗传算法的优化软件，使用matlab软件实现的，完成了算法的全部功能！(This is a genetic algorithm optimization software, the use of the matlab software to complete all of the features of the algorithm!)
