TutorielMatlab.pdf CE TUTO VOUS DONNE PERMET DE VOUS INITIER AU LANGAGE DE PROGRAMMATION MATLAB

doarima.m MATLAB script to do an ARIMA(p,d,q) analysis where d is set but P and q can be vectors of values you want to try. It produces AIC and FPE (final prediction error) values for comparing models. The AIC is different than the one computed by S+, but they both minimize on the same model for the arma22.dat simulated data.

图像加密程序，基于混沌系统的MATLAB实现(Image encryption, chaotic systems based on MATLAB to achieve)

PCA,KPCA完整程序，对研究人脸识别非常有用(this the code of pca and kpca)

基于RSSI的定位，已知发射节点的发射信号强度, 接收节点根据接收信号的强度, 计算出传播损耗, 利用理论的或经验的信号传播模型将传播损耗转化为距离, 然后再计算出节点的位置(RSSI-based positioning, known to launch the node transmission signal strength, the receiving node according to received signal strength, transmission loss calculated using the theory or experience loss of signal propagation model will spread into the distance and then calculate the location of the node)

基于GUI的计算器实现了基本加减乘除的计算机的功能，可以matlab仿真。(It is a good GUI.)
