使用PCA算法的人脸确认

这是我自己写的对图像进行预处理的matlab源程序，主要是对图像进行光照补偿、旋转与尺度归一化。上传上来和大家一起学习、分享。(This is I wrote it myself pretreatment image matlab source, mainly for image illumination compensation, rotation and scale normalized. From up and study together, to share.)

给水管网优化课本中的例题。计算井水管网的汇水管的水头损失。并且有图。(calculate the head lost of pipe net .)

这是一个用于实现GMRES算法的程序，可以通过修改源代码，实现不同的功能(This is a procedure used to implement GMRES algorithm, you can modify the source code for different functions)

线性卡尔曼滤波在温度测量、自由落体运动目标追踪、GPS导航定位、石油地震勘测、视频图像目标追踪中的应用(Application of Linear Kalman Filter in Temperature Measurement, Free-falling Motion Target Tracking, GPS Navigation and Positioning, Petroleum Seismic Survey and Video Image Target Tracking)

编写程序完成不同滤波器的图像频域降噪和边缘增强的算法并进行比较，得出结论,效果很好，多种方法工你选择，文档中包含图片( Image Frequency noise reduction and edge enhancement algorithms to program completion and compare different filters, concluded that the effect is very good, work a variety of methods to choose from, the document contains a picture)

this program simulates 1D electromagnetic Maxwell equations in "propagation in a lossy medium", by using finite difference time domain method FDTD

灰度预测模型，用于做评价，可更改。使用MATLAB实现。(Gray prediction model)

水声时延估计及蒙特卡洛实验，本代码为matlab程序语言，时延程序中有读取.dat文件，用户直接读取即可。本程序包含蒙特卡洛实验，程序中加油注释，用户可自行更改参数。

说明：  进行基于最大最小方法和K均值结合的分类方法 并画出具体的分类情况，对二维数组具有鲁棒性。(Based on max-min method and combination of K-means classification method and draw a specific classification of two-dimensional array with robustness.)
