线性调频信号是一种雷达常用的电磁波信号，当雷达信号检测到目标时候，反射后得到雷达回波信号，此时由于多普勒效应，信号的频率发生偏移，这个源码仿真出雷达检测到目标速度信息的回波信号。(LFM signal is a commonly used electromagnetic radar signal, when the radar signal detection to the target time, after reflection of radar echo signal, at this time due to Doppler effect, the signal)

一个计算均匀圆阵角度估计模糊集的程序。通过计算阵列流形的弧长参数，求得阵列的模糊生成集。(A calculation of the angle estimation with uniform circular arrays ambiguity set procedures. Array manifold by calculating the arc length parameter, obtained an array of ambiguity generating set.)

the attachment file is a matlab file about ODE. this include the rutine ODE45 of matlab.

基于matlab将商标与文字分割，选定阀值，先进行次分割，在进一步优化(Matlab-based trademarks and text segmentation, the selected threshold, the first for sub-division, in further optimization)

这是学习mathematica软件的经典教程，也是自学的好帮手，由著名的物理学家JIM HOSTE所著，并由MC GRAW HILL出版。希望对初学者有所帮助(This is a classic learning mathematica software tutorials, is also a good self-help, by the famous physicist JIM HOSTE book, published by MC GRAW HILL. Want to help beginners)

说明：  自己编写的计算光流场的MATLAB程序，基于梯度的方法，非常简单(I have written a MATLAB calculation of optical flow procedures, based on the gradient method and it is very simple)

伽辽金最小二乘无网格法、伽辽金配点无网格法等(伽辽金最小二乘无网格法、伽辽金配点无网格法等，其中许多内容都是作者课题组在国家自然科学基金资助下取得的成果。书中给出了作者用C++研制的面向对象的无网格法程序OMLL，另外各章都给出了相应的MATLAB 程序，以帮助读者理解各种无网格方法的程序实现过程。)
