This code generates a 10x10 matrix using magic(10) .find min and max in each row and save the info in magic.txt and magic.dat

光子筛孔均匀分布的例程，用于光子筛成像时使用(Uniform distribution of photon sieve routines for use imaging photon sieve)

语音信号的iir滤波器设计,从带有噪音的信号中提取原始声音.目前，MP3播放器一般功率放大器的工作频率范围就是这个范围。但是大部分有用的和可理解的信息的频率在200到3500Hz之间。所以我们可以在这个范围间滤波，达到使声音可理解的要求。现将数字滤波器的设计指标设为通带截止频率fb=600HZ,阻带频率fc=1200HZ,通带波纹Ap=1dB，阻带波纹As=40dB,要求确定H(z)。(design of the iir filter, get the original voice without noise)

本程序是建立了三维椭球随机分布模型，并绘制出分布图像。(This procedure is to establish a three-dimensional ellipsoid model of random distribution, and to map out the distribution of the image.)

此程序是针对文献《基于相关函数的多振动信号数据融合方法》撰写的matlab程序，属于多源信息融合(This program is for literature, " based on the relevant multi-function vibration signal data fusion," wrote the matlab program, part of multi-source information fusion)

说明：  因子分析法主程序，输入数据x以及主成分个数，则可以得到因子分析法的结果(Main factor analysis, the input data x and number of principal components, you can get the results of factor analysis)

说明：  基于matlab用神经网络的一组数预测，数学建模里比灰度预测好用(Een reeks nummervoorspelling op basis van matlab met behulp van een neuraal netwerk, wat beter is dan grijze voorspelling in wiskundige modellen)

一维功率谱密度计算程序，可以选择是否加窗，加那种窗(1D power spectral density caculation routin base on fft )

matlab编写的数字签名言简意赅，相信一定会有人用到。(matlab digital signature prepared concise, I am sure someone will use.)

说明：  matlab里支持向量机工具箱，好用(matlab in Support Vector Machine Toolbox, easy to use)
