该软件可实现传统的NMF非负矩阵分解，希望能对大家有所帮助！(This software can realize non-negative matrix factorization. I hope it is helpful for all of us.)

用matlab绘制Ackley函数的三维图形，(Using matlab draw the Ackley function' s three-dimensional graphics,)

说明：  Zigzag和iZigzag的程序及改进的Zigzag和iZigzag的程序。后者可以大幅提高运算效率(Zigzag and iZigzag procedures and improved Zigzag and iZigzag procedures. The latter can substantially increase the computing efficiency)

四步相移法程序和最小二乘法相位解包裹程序，已经验证，此方法比较不错。(Four step phase-shift method program and least squares phase solution package, have validation, this method is good. )

周期T=5，脉宽tao=1的矩形脉冲及频谱图(cycle T = 5, pulse width = tao a rectangular pulse and the spectrum)

program to compute 2d-maxima for a set of xy points. The xy data points are generated using a random number generator. The command to run the program at DOS prompt is: - compute 2d-maxima for 500 xy points .2dmaxima 500

主要是实现图像的融合,是在梯度域里面进行一个图像的融合，(shi xian tu xiang de rong he，in tidu yulimian rong he ercheng ,matlab huan jing,xia ,keyi yunxing qieyou ceshi shuju d e.)

展开相位是物体表面三维形貌测量中一项关键技术，为了避免相位展开过程中的误差传播效应，Saldner和Huntlye等提出了时间相位展开方法。用matlab模拟了时间相位展开的方法(Expand the phase surface 3D topography measurement of a key technology in order to avoid the phase unwrapping process of error propagation effects, Saldner and Huntlye temporal phase unwrapping. Using matlab to simulate the temporal phase unwrapping method)

实现文献‘Fast and robust multiframe super resolution’的仿真，程序中有详细解释，对于多帧超分辨率重建中，退化图像获得，如何进行迭代重建，都有详细说明。(Literature ' Fast and robust multiframe super resolution' simulation, the program explained in detail for the multi-frame super-resolution reconstruction of the degraded image, iterative reconstruction, there are detailed instructions.)

一种稀疏角度下的重建算法，该算法是在matlab平台上实现的CT重建算法(A sparse angle reconstruction algorithm)
