matlab齿轮设计程序，直齿轮，角变位齿轮 (matlab gear procedure )

说明：  Matlab工程应用基础详细讲解了工程上的实际问题(Matlab engineering works on the basis of detailed account of the practical problems)

齿轮形状可调，可分布不同齿形，大大节约作图时间，希望大家支持改进(The gear shape adjustable spread toothed significant savings plotting time, I hope you will support improved)

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

principle componant analysis based face recognition

说明：  Image Watermarking. It is used to water mark digital images using asymmetric method

说明：  MATLAB的一些例子，PPT格式，方便易懂(MATLAB some examples PPT format to facilitate easy)

这是包含丰富内容的流行学算法工具，里面有大量的MATLAB仿真示例，希望对大家有帮助(It contains rich content tools for popular school algorithm, which has a large number of MATLAB simulation example, we want to help)

Ritz法解决-u +u=x 0<x<1，u(0)=0,u(1)=0的有限元边值问题。精确解为u(x)=1/(exp(1)-1/exp(1))*exp(-x)+1/(1/exp(1)-exp(1))*exp(x)+x，基函数为g(i)=sin(i*pi*x)(This matlab code is used to solve the boundary value problem of the differential equation: -u +u=x 0<x<1，u(0)=0,u(1)=0, where the accurate solution is : u(x)=1/(exp(1)-1/exp(1))*exp(-x)+1/(1/exp(1)-exp(1))*exp(x)+x)
