说明：  该程序为文本文档，可在matlab 中运行(the procedures for text documents can be run in Matlab)

光子晶体的算法，一个关于光子晶体的比较有用的算法，还算可以用(The algorithm of the photonic crystal, a photonic crystal, the more useful algorithms, OK)

利用matlab对随机过程课程的仿真 1、利用matlab绘制随机过程的谱密度G_x (ω)=2αβ/(β^2+ω^2 ) (α、β为正数)的图像。 2、绘制白噪声的功率谱密度函数G_x (ω)=N/2和自相关函数R_N (τ)=N/2 δ(τ)的图像。 3、分析低通白噪声和带通白噪声的功率谱密度函数和自相关函数的性质并举例同时绘制其图像。 (1, drawn using a random process matlab spectral density G_x (ω) = 2αβ/(β ^ 2+ ω ^ 2) (α, β positive) image. 2 for the white noise power spectral density function G_x (ω) = N/2 and the autocorrelation function R_N (τ) = N/2 δ (τ) of the image. 3, the analysis of low-pass white noise and band-pass white noise power spectral density function and autocorrelation function of the nature and the examples at the same time to draw its graphics.)

The MATLAB Scripts (m-files) Simulate MIMO Communication System with Zero Forcing (ZF) Detection, Minimum Mean Square Error (MMSE) Precoding and Detection. It of course goes with the MAIN Programs which calls the functions.

说明：  实现异步电机无速度传感器控制，应用滑模观测器(The asynchronous motor is controlled without speed sensor and sliding-mode observer is applied)
