for calculating boundray segment

说明：  matlab编程实例一百个，非常有用的小程序，尤其是在图像处理方面。(matlab programming examples hundred, a very useful little program, especially in image processing.)

模拟PD雷达的信号处理程序，完成信号回波模拟，脉冲压缩，MTD等功能.(a program about pulse doppler radar signal processing.)

傅里叶变换和小波变换重建图像的比较效果，这个程序可以用来实现四个要求：1、FFT和WT重建效果比较；2、通过改变小波来比较重建效果；3、通过改变分解层数来比较重建效果；4、通过改变大系数个数来比较重建效果。其中还有一个计算PSNR的程序(the comparative effect of reconstruction image by Fourier transform and wavelet transform 。 the program can be used to achieve the four requirements: 1, FFT, and WT reconstruction effect 2, by changing the wavelet to compare the reconstruction effect 3, by changing the decomposition layers to compare the reconstruction effect 4, by changing the number of large coefficient of comparative reconstruction results. Including a procedure of calculating PSNR )

matlab程序用于地震波的特性分析 时频及频谱分析(Matlab program for seismic wave characteristic analysis Time-frequency and spectrum analysis)

matlab新增寻找极值点程序，较老的版本中没有次函数(matlab find new extreme point of procedure, not the older version of the second function)

此程序为MATLAB环境下编写的用于对图像的平均梯度进行计算 从而对图像的清晰度 图像的质量进行评价的代码。(This program is written in MATLAB environment is used to calculate the average gradient image sharpness of the image and thus to evaluate the image quality of the code.)

解释飞蜂窝用户和宏蜂窝用户之间的通信，以及他们的覆盖问题。(Explain the communication between femtocell user and macro cellular subscribers, and their coverage problem.)

使用matlab就行计算和求值偏微分方程组，提供一些程序语言参考(using matab to analyze the partial differntial problem)
