matpower简明教程，希望对初学者有用(matpower simple tutorial, I hope useful for beginners)

这是用matlab编辑的求解偏微分方程的一种方法隐式求解抛物型偏微分方程(This is edited using matlab a method of solving partial differential equations implicit solution of parabolic partial differential equations)

关于聚类的两篇文献，一篇是博士论文，一篇是硕士论文，有需要的可以下载看看。(On the clustering of two documents, one is a doctoral thesis, one is a master s thesis, there is a need can be downloaded to see.)

采用MATLAB环境实现无迹神经网络的源程序m文件啊，有价值(MATLAB environment to achieve unscented neural network source m file and valuable)

说明：  刘金锟先进PID第二版程序，需要的可以下载。(Liu Kun, the second edition of the advanced PID procedures needed can be downloaded.)

系统识别工具-ARX模型离线识别方法的matlab程序实现。(System identification tool-ARX model identified offline methods matlab program implementation.)

Partition index is a measure ofvalidity similar to partition coeGcient, based on using Pj = ci=1 (uij)m as a measure ofhow well the jth data point has been classi- 2ed. The closer a pixel is to a codebook entry, the closer Pj is to one. Ifa pixel becomes an outlier to all cluster centers, the value of Pj approaches 1=cm − 1, which is the minimum value it can have.

计算信号的短时傅里叶变换，对信号进行时频分析(Calculate signal short-time Fourier transform, the signal time-frequency analysis )

基于matlab的fft算法设计，由于matlab的fft是built in文件，在此提供一种编写fft算法的思路。(Based on the matlab fft algorithm design, as the fft matlab file is built in, this provides an idea of ​ ​ writing fft algorithm.)
