基于多线程机制的，利用Matlab编写，粒子群优化算法。目标变量采用归一化处理，适用于所有的优化函数。优化函数自定义为fitness(x)。(Based on multi-threading mechanism, the use of Matlab to prepare, particle swarm optimization algorithm. Target variables using normalized treatment applies to all of the optimization function. Since the optimization function is defined as fitness (x).)

正弦信号产生一个具有两个正弦信号向量，本设计中运用continuous-state space s-function模块对输入信号进行变换，并通过scope模块显示出来。压缩文件中提供了M文件s-function的编写，以及搭建的模型框图(Generate a sinusoidal signal with two sinusoidal signal vector, the design of the use continuous-state space s-function module to transform the input signal and display module through the scope. Zip file provided in the file s-function M in the preparation and structures of the model diagram)
