关于算法设计最经典的教材，非常值得阅读，对一些较经典的算法都进行了详细的介绍(On the algorithm design and classic materials, well worth reading, for some of the more classical algorithms have carried out a detailed introduction)

说明：  对振动加速度信号进行逆傅里叶变换，支持Excel和text读取，希望大家批评指正(The inverse Fourier transform of the vibration acceleration signal supports the reading of Excel and text. I hope you can criticize and correct it)

这是三组程序，分别计算hibert变换，小波时频分布，wigner-vill分布，并且画出谱图(This is three groups of program, calculate hibert transform, wavelet time-frequency distribution, wigner- vill distribution, and draw the spectrogram)

Simulink all digital pll with fixed point

演化算法标准测试函数CEC2006,括Matlab代码，JAVA，C代码。(Problem Deˉnitions and Evaluation Criteria for the CEC 2006 Special Session on Constrained Real-Parameter Optimization)

差分进化算法DE，及检验函数Goal。5个检验函数用来验证DE算法的有效性。(Differential evolution algorithm DE, and test function Goal. The five test functions are used to verify the effectiveness of the algorithm of DE.)

基于马氏距离时间序列分类Time-series-classification-master(Time-series-classification-master)

计算超混沌Rossler吸引子的Lyapunov指数(calculated hyperchaotic Rossler attractor of Lyapunov exponent)

MATLAB教程，比较详细，可以作为工程设计工具书实用(matlab jiaocheng)

经典模态分解后对其中某一模态层绘制时频曲线(Empirical Mode Decomposition and time-frequency distribution)
