dipole-antenna

This technique doesn t involve sorting of probabilities as in Shannon-Fano coding. The following formula is used to calculate F (x) which in turn generates the code F (x) = F(x) + p(x) / 2, where F(x) is cummulative sum of probabilities p(x). It can be further understood with the following C code

模拟退火程序，用MATLAB语言实现，并带有程序算法说明(simulated annealing)

介绍了机器人的运动学的求解过程，对于初学者有很好的知道作用(Describes the process of solving robot kinematics, good for beginners to know the role of)

本程序是对双桨双舵船舶的回转运动进行操纵性模拟(This procedure can the simulate the rotary motion of a ship with twin-screw and twin rudder)

This simulation demonstrates the use of the PMSM in a closed-loop speed and current control on a 1.1 kW 3000 rpm industrial motor. A three-phase motor rated 1.1 KW, 220 V, 3000 rpm is fed by a PWM inverter. In this simulation, the whole system is built entirely with standard Simulink blocks (without resort to blocksets).
