计算一维光子晶体透射率的程序, 可以手动输入任意序列, 程序只针对两种介质组成的序列.(One-dimensional photonic crystal transmission process, you can manually enter any sequence, the program only for sequences composed of two media.)

自己做的一个针对mdb中数据集构建拓扑，并进行拓扑验证的例子，之前找半天没有找到相关的，自己做的这个还是可以用的，希望能帮到有需要的人士(Examples of their own to do a build topology for mdb data sets and topology verification, before looking for a long time did not find the relevant own doing this can still be used, I hope to help those in need)

主成分分析法，用于将低数据维度，减小有相关性的数据特征。(dimensionality reduction)

function g=distance_classify(A,b) 距离判别法程序。 输入已分类样本A（元胞数组），输入待分类样本b 输出待分类样本b的类别g 注：一般还应计算回代误差yita 输入已知分类样本的总类别数n 每类作为元胞数组的一列(function g = distance_classify (A, b) from the Criterion procedures. Input samples have been classified A (cell array), the importation of samples for classification b output samples for classification g categories b Note: the calculation should also be back on behalf of the general error input yita of the total known types of classification of the number of samples n each Cellular-type array as a)

function [g, badg] = numgrad(fcn,x,varargin)

强主动声纳信号干扰被动声探测的仿真分析.被动声探测是探测和跟踪水中噪声目标的重要手段,但强主动声纳信号的出现将对被动声探测产生很强的干扰作用,影响被动声纳对噪声目标的检测或跟踪。本文通过计算机仿真,分析被动声纳的积分时间、强主动声纳信号的强度、脉冲宽度和发射周期四个因素对强主动声纳信号干扰被动声探测程度的影响。(Simulation analysis of passive acoustic detection of a strong active sonar signal interference passive acoustic detection is an important means to detect and track water noise goals, but the emergence of strong active sonar signal will be passive acoustic detection generate strong interference effect, the impact of passive acoustic satisfied noise target detection or tracking. This paper through computer simulation, and analysis of the four factors of the integration time of the passive sonar, a strong active sonar signal intensity, pulse width, and launch cycle impact of passive acoustic detection of a strong active sonar signal interference.)
