cmx823调制解调器，单音频解码器件。(cmx823 modem, a single audio decoder device.)

HHT(hilbert haung transform)

说明：  popfnn神经网络，它是一种模糊伪输出的神经网络(pseudo-outer-production fuzzy nerual network).可用于模式识别。运行pop1可以训练输入的特征向量，extractionpop使用来抽取图片的特征向量的。(popfnn neural network, it is a pseudo-output fuzzy neural network (pseudo-outer-production fuzzy nerual network). can be used for pattern recognition. Can be trained to run pop1 input feature vector, extractionpop used to extract the image feature vector.)

说明：  matlab sym格式转换成char型和数值型的简易算法(sym convert to char or num simple algorithm )

一种图像拼接技术，是一个内嵌拼接。基于特征点的图像内嵌技术，里面有测试图像。(An image display technology, is an inline splice. Image based on feature points embedded technology, there are test images. Embedded image)

能够实现声音信号的时域、频域、相位、功率谱分析(this matlab codes can realize the function analysis of time domain, frequency domain,phase ,powerspectrum ect for a noise signal)

磁悬浮小球Simulink仿真，PID控制，适合磁悬浮系统初级学习(Magnetic levitation ball Simulink simulation, PID control, suitable for the primary study of the magnetic levitation system)

matlab实现thomas算法对三角矩阵解线性方程组(matlab thomas algorithm to achieve the solution of the triangular matrix of linear equations)

this code is for REAL-valued signals. An implementation of JADE for both real and complex signals is also available from http://perso.telecom-paristech.fr/~cardoso/guidesepsou.html

关于多体动力学很好，很全面的书籍，既有刚体也有柔性体(the book is about dynamics of multibody,include rigidbody and deformable body)
