此代码为三维菲涅耳全息图的再现代码，但是有部分错误还未完全研究明白(This code for the three Wei Feinie ears hologram reproduction code, but some of the error is not fully understood)

how to create sin signal in matlab

一本很好的傅里叶光学学习教材，英文原版，相当难得(A good learning material on Fourier optics, the English original, very rare)

matlab code for pso Particle Swarm Optimization Research Toolbox

说明：  有源功率因数校正仿真模型，采用滞环电流控制的方法。(The simulation model of active power factor correction adopts the method of hysteresis current control.)

在一个圆柱体上用二维棉片来模拟树皮表面的粗糙效果(cylinder in a two-dimensional cotton used to simulate bark film surface roughness effects)

需要将音乐文件bhk_med.wav放于D盘根目录下才可以直接执行程序，或将程序中的音乐文件路径指向当前目的音乐所在的地址。背景音乐可以更换，甚至可以自行合成。(Music files need to be put in the D bhk_med.wav root directory before you can run the program directly, or to program the music file path to the address of the current purpose of music is located. Background music can be replaced, even on their own can be synthesized.)

改进的粒子群算法，与遗传算法，神经网络，模拟退火等算法相结合(An improved particle swarm optimization algorithm combined with genetic algorithm, neural network, simulated annealing algorithm and so on)

本程序为用matlab对kalman滤波进行目标跟踪的应用仿真的程序代码(The procedures for the use of matlab kalman filter for target tracking application simulation program code)

matlab上课课件，word格式，初学matlab者很有帮助。(matlab class courseware, word format, matlab are very helpful to beginners.)
