Vector control of induction motor using matlab simulink

Steganography for images

用于计算两幅图像之间结构相似性度量的MATLAB源码(An implementation of the algorithm for calculating the Structural SIMilarity (SSIM) index between two images)

本文档内的源码 内容为图像分割技术在matlab中的代码 适合初学者和matlab爱好者(The source of the content within this document image segmentation code in MATLAB for beginners and Matlab lovers)

this program is for bwfw power flow.

Fit time series Q(t) to a logistic function. Inputs (vectors of same size): t (time) & Q Outputs: Qpre (logistic model fit to data) and three independent parameters: thalf, Qinf, and a, describing the logistic Q(t) = Qinf/(1 + exp(-a*(t-thalf))) Qinf is value as t --> infinity thalf is time of symmetric inflection point a is time decay constant Written by James Conder, Southern Illinois University, Oct. 2010

说明：  颜色阈值分割，可以很好的分割图像。希望对大家有用(Color segmentation, image segmentation can be very good. Hope to useful)

BP算法，异或和认证，本人数据挖掘小作业(BP algorithm, XOR and certification, data mining operations)

水文时间序列 每旬的极端事件计算，该指标用于混沌计算前期处理(Hydrologic time series of extreme events is calculated every ten days, the index is used to calculate the pre-treatment of Chaos)

实现加权最小二乘拟合，经典的系统辨识方法，很管用(Achieve a weighted least-squares fitting, classical system identification methods, it is useful)
