一维到三维算法，其中包括有各种散射体形状的示例，是用matlab编写的程序(One-dimensional to three-dimensional algorithm, which includes a variety of scattering of the shape of the sample, is a program written in matlab)

It s easy to get scattering of particle with Mie theory. However, is it possible to get the optical property from experiment scattering spectra? See this inversion Mie theory....

k-means clustering is a method of vector quantization, originally signal processing, that is popular for cluster analysis in data mining. k-means clustering aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean, serving as a prototype of the cluster. This results in a partitioning of the data space into Voronoi cells.

说明：  一本非常经典的书，INTRODUCTION TO MATLAB FOR ENGINEERING STUDENTS，国外很多著名大学学习Matlab就用的这本教材(This book, INTRODUCTION TO MATLAB FOR ENGINEERING STUDENTS, is a very good book.)

非常好的matlab的仿真教程，Simulink电路分析应用，有需要的可以看看。(Very good Matlab simulation tutorial, Simulink circuit analysis applications, there is a need to look.)

多种降维方法的一个程序包，包括PCA,ISOMAP, LLED等,GUI，界面直观简单(A variety of dimensionality reduction method package, including PCA, ISOMAP, LLED etc., GUI, simple and intuitive interface)

this file is a Recursive least square algoritm in matlab

说明：  用matlab实现信号处理，利用matlab强大的数据处理能力可以实现信号的处理(Using matlab to achieve signal processing, data processing using matlab powerful signal processing capability can be achieved)

里面有三个二维模糊调节器分别实现PID控制器的参数Kp，ki，Kd，的调节。其控制原理：根据前面的偏差e和偏差变化ec将三个模糊控制器FC1,FC2,FC3分别进行模糊化，模糊逻辑推理，解模糊化。最后得到pid控制器参数调节量。(There are three-dimensional fuzzy regulator PID controller parameters Kp, ki Kd, adjust. The control principle: the front of the deviation e and error change ec three fuzzy controllers FC1 has FC2, FC3, fuzzification, fuzzy logic inference, defuzzification. Finally, get the pid controller parameter adjustment.)
