DFT

TDOA matlab实现对信号的时延估计，代码量少，经过验证(TDOA matlab implementation of the signal delay estimation, less code, proven)

dw检验Matlab源码，傻瓜型，检测值矩阵已经在程序中准备好了，无需查询。直接导入数据出结果。解压后为m文件(dw test, easyused，import the data directly to the results. detection value matrix have been ready in the program, without having to query.)

实现快速傅里叶变换函数的matlab程序，以2D作为基来写的(Fast Fourier transform function matlab program to 2D as a base to write)

生成反射系数的，希望对大家有帮助,是我们实验室用做地震资料处理流程中合成地震反射系数用的，具体看程序就知道。(you can see chinese explane,)

数据降维与流形学习，方便初始学者学习数据降维方法和流形学习。(Data dimension reduction and manifold learning)

filter responce on pulse with fft

利用分步傅立叶积分法，计算了光纤中色散与SPM效应(Step-by-step use of Fourier integral method, the calculation of the fiber dispersion and SPM.)

基于粒子管理器的粒子群算法研究 粒子群优化算法进化(Population Manager of PSO)

A set of functions to crop polygons or compute are of polygons intersection.
