Matlab程序设计与应用,从基础叫如何用MATLAB编程和它的强大运用(Matlab program design and application, from basic told how to use MATLAB programming and the use of powerful)

induction machine mathematical model

有限差分法中简单迭代法计算场域节点的应用(Finite difference method in a simple iterative method to calculate the application node)

说明：  根据轴承实验数据，处理轴承内外圈的实验数据，根据频谱进行数据分析。(According to the bearing experimental data, the experimental data of bearing inner and outer rings are processed, and the data are analyzed according to the spectrum.)

关于PCA算法的调用程序，傻瓜式操作，直接运行，附带样本数据文档，很好的帮助初学者。 一看就懂！可以任意更改样本！(Calls on the PCA algorithm procedure, Fool operation, direct running, with sample data files, a good help for beginners. Understand at a glance! Samples can be changed!)

That is a program, about frequency and digital siglal processing. It is a .m file, that is developed for Matlab environment.

对数据先进行经验模态分解得到不同特征尺度的信号分量，然后对所有的信号分量用AR模型进行预测得到预测后的分量，然后将预测后的分量进行重构得到最终的预测信号。(The data first empirical mode decomposition characteristics of the signal components of different scales, and then for all signal components obtained by AR model to predict the component forecasts, and then predict the components are reconstructed to obtain final predicted signal.)

用Matlab实现的人工免疫系统, 非常全面。(Implementation of artificial immune system in matlab.)
