粒子群优化算法，粒子群优化算法基本流程，稍加修改即可应用(Particle Swarm Optimization)

此文件实现了让语音信号通过低通，高通，带通滤波器使其变声，并且在GUI界面上绘出了个滤波器的频率响应和语音信号的频谱。(This file allows to achieve a voice signal through a low pass, high pass, band pass filter to make it change the sound, and plotted on a GUI interface and voice signal spectrum frequency response of a filter.)

说明：  直接序列扩频通信，完整系统,包括伪随机码产生，扩频，调制，加噪，解调，解扩等(Spread Spectrum System)

找到了本征模式，运用matlab语言编写的程序，对科技工作者有很有帮助，可以解决maxwell方程(found a pattern of the levy, using the Matlab language procedures, right technology workers are helpful, maxwell equation can be solved)

给定一个普通多项式p(x)，用列向量表示，阶次从高到低排列，此函数返回p(x)的切比雪夫多项式展开的系数，返回的的结果也是一个列向量，同样按切比雪夫多项式的阶次从高到低排列(Given a general polynomial p (x), with a column vector representation, the order highest to lowest, the function returns p (x) Chebyshev polynomial expansion coefficients of the returned result is a column vector, the same press cut the order highest to lowest Chebyshev polynomials)
