用离散傅里叶变换编写的人脸识别的代码，基于matlab平台，附带了专用的用于识别的人脸图片(Face recognition code using the discrete Fourier transform, based on matlab platform, comes with face photos dedicated used to identify)

Encrypt a picture using DES

this coding use for students who use matlab steganography. the code will be highly used in recent times.

说明：  基于主分类分析的SAR图像变化检测MATlt实验程序(Based on the analysis of the main SAR image classification change detection experiment)

基于时延估计的目标定位与跟踪：编写了一个Matlab GUI，可以实现三围空间目标的定位，以及运动目标的跟踪(The Target_Positioning_&_Tracking Through Time-Delay-Estimation.)

this program is helpful in calculating the span of the knot vector in bspline

利用MATLAB产生三角波的模型， 功放模型仿真中的三角载波，经过测试，数据还是比较准确的(Using MATLAB to produce triangle wave model)

直方图均衡。 不利用MATLAB自带的histeq.m函数，自己编写主函数进行直方图均衡化处理(hist equal)

仿真分析了FFT的补零、泄露、加窗、以及FFT分辨率等问题(Simulation analysis of the FFT of zeros, leakage, windowing, and FFT resolution issues)

演示对称振子天线的立体方向图，此程序为动画效果的程序。(Demo three-dimensional symmetric dipole antenna pattern, the procedure for animation programs.)
