This is a case where a array is introduced filtered

说明：  将pca和elman神经网络结合起来，找到了主要的变量(The PCA and the Elman neural network to combine to find the main variables)

李雅普诺夫指数的验证，只要进行变换器分岔混沌的研究(vertify Lyapouve exponent)

说明：  智能算法三十例，matlab版，希望对大家有用，真心要好好学习一下(this is very good and helpfull to you!)

巴特沃思滤波器matlab程序处理，包含高通、低通等等(butteword filter)

说明：  kurtogram是一种四阶谱分析工具，用于检测和表征信号中的非平稳性。可用于轴承的故障诊断(The kurtogram is a fourth-order spectral analysis tool elaborated for detecting and characterising nonstationarities in a signal. It relies on the assertion that each type of transient is associated with an optimal (frequency/frequency resolution) dyad (f ; Df) which maximises the kurtosis. The Fast Kurtogram computes the kurtogram over a grid that finely samples the (f ; Df) plane. Its complexity is on the order of N log N. This is the "plain vanilla" code used in paper: J. Antoni, Fast Computation of the Kurtogram for the Detection of Transient Faults, Mechanical Systems and Signal Processing, Volume 21, Issue 1, January 2007, Pages 108-124.)

一个很好的matlab学习讲义，很有针对性,思路清晰，重点和难点突出。具有很高的参考和学习价值.(It is a very useful tool for your learn of matlab.The thinking is clearly, important and difficult points is outstanding.So it has high value of reference and study.)

matlab数值算法的中文版书籍，详细介绍基于matlab的各种数值算法。(The Chinese version of the numerical algorithm matlab books, matlab detailed Numerical Algorithms based presentation.)

主要用于故障诊断的神经网络预测KPCAcontourmap代码文件(Neural Network Prediction KPCAcontourmap Code File for Fault Diagnosis)

机器人的simulink模型，能够看到原代码。希望对你的学习有所帮助。(robot Simulink model will be able to see the original code. You want to learn some help.)
