ProbShrink for color image denoising

主成分分析（PCA)算法是用于简化数据的一种技术,对于某些复杂数据就可应用主成分分析法对其进行简化。

measuring Date quality using fuzzy interpreter, the type of file is .fis.

自编的几个关于数字信号基本运算的程序，由此可以大大扩展信号运算的自由性与简洁性。(wrote several digital signal on the basic operations procedures, It can be greatly expanded signal operation and the freedom of simplicity.)

说明：  用subplot，imshow，imread，遍历并显示图库文件夹中的人脸图像（用循环）。运行后图像要显示成矩阵模式的，还得产生统一矩阵和均值矩阵。(With a subplot, imshow, imread, traverse and display the Gallery folder of face images (with circulation). After running into the matrix mode to display images, and have to produce unity matrix and the mean matrix.)

关于电力系统暂态稳定短路计算的一些源程序同时是有关matlab优化的源程序(Short circuit on the power system transient stability calculation of some of the source code is also optimized for matlab source code)

Calculate a gradient by using a mask (sqrt(R² + I² ).(Calculate a gradient by using a mask (sqrt(R² + I² ).)

说明：  针对MATLAB的优化功能，本人特别整理了MATLAB常用的优化工具箱代码(MATLAB function for optimization, I used the special finishing of the optimization toolbox of MATLAB code)

Identifying overlapping period in time series. Required input: X = structure with in every cell (X{cell}) a measurement station. every cell has its first three columns as [year,month,day] Output: begin_date = is beginning date of overlapping periods end_date = end date of overlapping periods output = structure with overlapping periods filtered numcell = number of measurement stations
