pca和kpca程序，对大家有很大的帮助，系统辨识和故障识别，很有用的，谢谢(Pca and kpca program, to all have a big help, system identification and fault recognition, very useful, thank you )

用matlab建立光学综合孔径望远系统的仿真程序，包括成像系统的MTF分析及图像重构。(Image Reconstruction Technique of the Optical Synthetic Aperture in the Telescope )

基于KL散度的NMF算法的实现，收敛性证明可以参考：Lee D D, Seung H S. Algorithms for Non-negative Matrix Factorization[C]// NIPS. 2000:556--562.(Implementation of NMF algorithm based on KL distance)

H=CIRCLE(CENTER,RADIUS,NOP,STYLE) This routine draws a circle with center defined as a vector CENTER, radius as a scaler RADIS. NOP is the number of points on the circle. As to STYLE, use it the same way as you use the rountine PLOT. Since the handle of the object is returned, you use routine SET to get the best result.
