产生周期大于500的逆M序列matlab程序。(The inverse M-sequence production matlab program.)

-给原始的语音信号加上一个高频余弦噪声，频率为5kHz。画出加噪后的语音信号时域和频谱图--(- To the original speech signal with a high-frequency cosine noise, frequency of 5kHz. Draw the speech signal with noise after the time-domain and frequency spectrum-)

it is useful to one who are study GA. I hope it can hope you ,i will very happy.

comsol仿真计算发射和反射波，并在第一和第二衍射级作为入射角为一个导线栅的电介质基片上的角度的功能的衍射效率。平面波的入射角扫从垂直入射到掠入射。本申请还示出了用于发病的一个选定角度的多个光栅周期的电场范图。(This application computes diffraction efficiencies for the transmitted and reflected waves and the first and second diffraction orders as functions of the angle of incidence for a wire grating on a dielectric substrate. The incident angle of a plane wave is swept normal incidence to grazing incidence. The application also shows the electric field norm plot for multiple grating periods for a selected angle of incidence.)

关于PCA算法的调用程序，傻瓜式操作，直接运行，附带样本数据文档，很好的帮助初学者。 一看就懂！可以任意更改样本！(Calls on the PCA algorithm procedure, Fool operation, direct running, with sample data files, a good help for beginners. Understand at a glance! Samples can be changed!)
