经典的二阶矩四阶矩信噪比估计，有不经过上采样、成型滤波和经过上采样、成型滤波的两种版本。加噪方式也分别用了matlab自带函数和自写两种版本。望大家参考。(Second Moment classic SNR estimation fourth moment, there is not through the sampling, the shaping filter and sampled, two versions of shaping filter. Plus noise mode were also comes with a matlab function and self-written versions. Hope you reference.)

可用于高光谱图像处理的自己编的PCA函数,Matlab版的.主要作用是降维.(the pca function is used to hyperspectral image processing.)

用matlab中的guied 制作的用于 数值分析课程教学的 数值实验平台，包括插值法、样条法、分段解析法等(Create with the guied in the matlab of used for the number experiment of number analysis course teaching platform, include to put to be worth method and kind method, and cent segment resolution method...etc. )

一本经典的关于光子晶体的书，由John于1987年编写，是学习光子晶体的人不可错过的好书(A classic book on photonic crystals, prepared by the John in 1987, is the study of photonic crystals books were not to be missed)

regulator matlab simulation PID control is ubiquitous. While simple in theory, design and implementation of PID controllers can be difficult and time consuming in practice. PID control involves several tasks that include:
