matlab program to calculate force.

matlab对aloha，s-aloha，csma的仿真(matlab pairs of aloha, s-aloha, csma Simulation)

By the harmonic elimination technique,we can solve for the switching angles of a half bridge to cancel the 5th, 7th, 11th and 13th harmonics by the Newton Raphson iteration technique.

MATlab避障控制算法 需要安装Tomlab工具箱，比matlab自带工具箱更具有优点！(MATlab obstacle avoidance control algorithm will need to install Tomlab toolbox, matlab own toolbox more than the benefits!)

希望给辛苦科研的人带来一点点帮助--学习因子可以变化的PSO算法，不再是c1=c2=2，粒子进化更加灵活，下面是学习因子同步变化的pso，调用形式为[xm,fv]=LNCPSO(fitness,N,cmax,cmin,w,M,D)(People who want to work hard to bring a little bit of research to help- learning factor can vary PSO algorithm is no longer c1 = c2 = 2, particle evolution is more flexible, learning factor is below synchronous changes pso, calling in the form of [xm, fv] = LNCPSO (fitness, N, cmax, cmin, w, M, D))

关于小波的matlab四种变换，研究小波应用的很需要(on four Matlab wavelet transform, the application of wavelet research is needed)

matlab simulink 实现TCM网格编码调制仿真。较好调试。(Matlab Simulink TCM Trellis Coded Modulation simulation. Better debugging.)

Matlab源码，主要采用时域有限差分(FDTD)法实现1D、2D的电磁仿真。(This directory contains MATLAB files for 1D simulations of electromagnetic fields. Included are wave propagation in free space, in dissipative media (sigma nonzero), and in dispersive media (debye medium).)
