此算法是著名的流行学习算法，可以用于数据特征的提取，维数约减等操作。(This algorithm is a famous and usefule algorithm for extrating the fature or reducing the dimension.)

this commande is very robust for moabile robot

PSO_A Alogrithm ,Hybrid particle swarm-based-simulated annealing optimization algorithm

Unitire轮胎模型与滑移率的Simulink模型(Simulink Model of Unitire Tire Model and Slip Rate)

Viterbi Algorithm & Viterbi Decoder Matlab Code.(Provided both soft & hard decision ability). Note: The main function is viterbi.m

duffing方程的混沌判别中使用到了庞加莱截面，即多维相空间中适当选取一截面 ，此截面不与轨线相切，不包含轨线，且便于观察系统的运动特征变化.(use Poincare chaotic duffing equation discriminant, multi-dimensional phase space appropriate to select a cross-section, this section is not tangent to the trajectory does not contain the rail line, and easy motion characteristics of the observed system changes.)

It will make negative of input image

求N个字符的不重复排列数，不是标准的递归写法，供求职时笔试参考。(Seek N-character array of non-repetition number, not an ordinary recursive formulation for the job when the written reference.)

用matlab编写得计算器，很好用得，不妨(Matlab prepared using a calculator, a very good use might be)

说明：  实现了sift算法,全部是用matlab写的，很实用(realize the sift)
