i have written the code for linear classifier for n classes.

说明：  天线相关性方面的仿真，已经验证过，可以使用(Antenna Simulation relevance has been verified, you can use)

PSOt is different of PSOrt, because you can choose differents mode of convergence

MATLAB Development and Application of the Finite Element

绘制控制系统近似bode图，为了做自动控制原理作业时偷点懒。虽然matlab自带bode函数但是作业要求画近似的。(Drawing control system approximation bode diagram, when you steal lazy to do the job of Automatic Control Theory. Although matlab function but the job comes bode asked to draw approximate.)

AR过程的线性建模与功率谱估计，计算其自相关序列的估计，利用所估计的自相关值和Yule-Walker法(自相关法)，估计系数值。(The linear AR process modeling and power spectrum estimation, calculation of the estimated autocorrelation sequence, using the estimated autocorrelation values and Yule-Walker method (autocorrelation method), the estimated coefficient.)

一个集合遗传算法，蚁群算法，粒子群算法的混合算法解决TSP问题的MATLAB程序(A collection of genetic algorithm, ant colony algorithm, the hybrid particle swarm optimization algorithm to solve TSP problems MATLAB program)

matlab空间后方交会程序 实现空间后方交会程序(matlab space resection procedure)

OFDM系统仿真Matlab程序（参数对照2K模式，映射使用4QAM）(OFDM system simulation Matlab program (2K mode control parameter mapping using 4QAM))

ESPIRT算法的matlab仿真，基于旋转因子不变形doa估计算法。只适用于均匀线阵。(ESPIRT algorithm matlab simulation, based on the rotation factor is not deformed doa estimation. Applies only to uniform linear array.)
