matlab编写的信号分解，采用HHT变换的EMD分解方法，提取信号的各阶EMD分量。(matlab write signal decomposition, the use of HHT transform EMD decomposition method to extract the signal component of each order EMD.)

there is a matlab cod for Autonomous system, that describe to compute trajectory and point of the system, and plotting it.

使用matlab编写的m文件，可以求出图像处理后的峰值信噪比(Matlab prepared using m-file, you can find the peak signal to noise ratio of the image processing)

这是nmflab的操作指导书，可以当成一个工具箱添加到matlab中，其中包含nmf几种经典的算法，很有指导意义！(This is the operating instructions nmflab can be added as a toolbox to matlab, which contains nmf several classic algorithms, is very instructive!)

利用超晶胞和平面波方法计算了长方格子圆柱光子晶体的能带结构(hyper-cell and plane-wave method to calculate the long-square cylindrical photonic crystal structure of the band)
