基于四阶累积量的联合对角化，其中给出两种四阶累积量计算方法，方便理解。这个算法还是比较难的，可以参看下独立分量分析中的jade算法(Fourth-order cumulant-based joint diagonalization, which gives two fourth-order cumulant method, easy to understand. This algorithm is quite difficult, you can see under the jade independent component analysis algorithm)

对adc采样信号进行频谱分析，计算信噪比，有效位数等等重要参数(Adc sampling signal for spectrum analysis, calculate SNR, the effective number of bits so the important parameters)

sift算法的应用实例，对于做图像处理的初学者相当有用。(sift algorithm application example, image processing, for doing very useful for beginners.)

in this discussion is about the electrical technology how it is changing day by day

这是一个半导体激光器弛豫振荡现象的仿真程序，计算参数和速率方程模型都取自经典教材Semiconductor Lasers(Agrawal 著)，可以作为学习和进一步研究半导体激光器各种动态特性的基础材料。(This is a simulation program by Matlab for calculating the oscilating in semiconductor lasers, in which the rate equation model and the parameters used are all from the classic technical monograph by Agrawal. This could be a basic material for further investigating and studying different dynamic activities of semiconductor lasers. )
