matlab程序设计的源代码，有利于初学者了解MATLAB的编程思想与方法，使初学者快速入门(Matlab programming source code, be helpful for beginners to learn matlab programming thought and method, make the beginner quick start)

灵敏度分析源程序，可用于结构模型修正，但仅运用了自振频率信息，没有运用振型信息(Sensitivity analysis of source code, can be used for structural model updating, but only the use of natural frequency information, there is no information on the use of modal)

HDB3码 连“0”个数计数 V脉冲位置记录变量B脉冲位置记录变量 让0000的最后一个0改变为与前一个非零符号相同极性的符号......(Even HDB3 code " 0" count the number of pulse position record variable B V pulse position to make 0000 a record variable is changed to 0 and the last one before a non-zero symbol of the same polarity sign ......)

希尔伯特黄变换程序，里面还有emd变换的程序，希尔伯特黄变换的画图工具，能画出模态函数瞬时频率图像(Hilbert-Huang transform procedures, there EMD transform procedure, and the instantaneous frequency of the Hilbert-Huang transform image)

PI仿真simulink的模糊控制，基于simulink和设计的模糊控制块设定的闭环pid控制(Simulink simulation of fuzzy control PI)

一种常用的神经网络算法，根据实际的输入与输出数据，计算模型参数(Artificial Neural Network Calculate model parameters based on actual input and output data)

说明：  通过非线性动力学中混沌研究的poincare图可以很方便的识别出周期，拟周期或者混沌运动，该程序实现了poincare图的绘制(Through the study of nonlinear dynamics in the chaotic poincare map can easily identify periodic, quasi-periodic or chaotic motion, the program achieved poincare mapping)
