this is k-means clustering algorithm codes in matlab, and it is for beginners

对混沌时间序列相空间重构中最佳延迟时间间隔和嵌入维数的选取方法作 了综述,提出了同时考虑这2 个参数选取的重构展开虚假邻点法以及预测误差最小(Of chaotic time series phase space reconstruction of the best delay time interval and the embedding dimension of the selection methods were reviewed and put forward these two parameters taking into account the reconstruction of the selected start-point method of false neighbors, as well as the minimum prediction error)

说明：  整个系统分为数据采集和数据分析两大部分，以友好的图形界面与用户进行交互沟通。 声音数据采集部分实现数据采集功能,根据用户选择的采样频率和预设的采样时间来从声卡获得用户需要的数据。并且将采集到的数据及其频谱图以图形方式很直观的呈现于用户面前。 图像采集分析部分，读入图像后，根据选择，对其进行Linear Conformal、Affine、Projective、Polynomial、Piecewise Linear、Sinusoidal、Barrel、Pin Cushion变换(The whole system is divided into data collection and data analysis of two parts, with a friendly graphical interface to communicate with the user interaction. Sound data collection part of the data collection function, according to user-selected sampling frequency and sampling time to the default user from the sound card to obtain the data needed. And the collected data and the spectrum is very intuitive graphically presented in front of the user. Image acquisition and analysis section, read the image, based on the choice of its Linear Conformal, Affine, Projective, Polynomial, Piecewise Linear, Sinusoidal, Barrel, Pin Cushion Transformation )

emd code for calculate emprical mode dicompistion

自己编写的matlab函数用于对图像倾斜进行自动校正，效果非常理想，对于条纹形的图像。(I have written matlab function is used to automatically correct image tilt, the effect is very ideal for stripe-shaped images.)

MATLAB/simulink光伏电池建模！！！！(Photovoltaic cell modeling)

说明：  simulink里搭的并网逆变器单环电流控制，matlab版本2013a(Single loop current control of grid connected inverter, matlab version 2013a)

image processing-filter

卡尔曼滤波的源代码，里面包括了权向量的计算以及MSE的偏差曲线(Kalman filtering of the source code, which includes the calculation of the weight vector and the MSE deviation curve)

code is matlab which is thrshold code
