this is a FFT algorith using by matlab code

Matlab非平稳时间序列，很经典啊！，谢谢这个网站(Matlab non-stationary time series, classic ah! Thank you, this site)

使用相关函数来检测信号序列中隐含的周期性(Using the relevant function to detect the implicit periodic of signal sequence.)

电磁波、声波或地震波等数值模拟中常常会用到有限差分法，但是很多文章都只是泛泛而谈时间2阶，空间4阶等等如何用公式，本文给出了任意阶精度的泰勒展开与迭代公式。(Numerical simulation of electromagnetic, acoustic or seismic waves will often use the finite difference method, but many articles are just generalities time two bands, space, etc. How to order 4 formula, this paper presents the accuracy of any order Taylor expansion and iterative formula.)

黑油模型数值模拟入门指南 市场上有不少关于油藏数值模拟的书，但好像没有类似围棋入门指南那样从基础开始一步 一步介绍的书。我收到不下二十个问油藏数值模拟如何入门的问题。我尝试写一写油藏数值模拟 入门指南，希望对那些刚刚开始进入油藏数值模拟领域的工作者有所帮助(Numerical simulation of black oil model Start Guide on the market, many of reservoir simulation, but it seems there is no similar entry guidelines go as the beginning of step by step from basic introductory book. I have received no less than 20 reservoir simulation asked how the issue of entry. I try to write to write a reservoir simulation Start Guide, I hope for those just beginning to enter the field of reservoir simulation will help workers)

可以对某一块海洋区域进行纵切断面，并在一张图上生成几个图片(Can conduct a longitudinal section of a marine areas, and generate a few pictures on a map)

非常好用的小波去噪程序，里面代码注释详细，为本人硕士论文过程中编写。(A series of Data Denoising Theroies.Very helpful.)

运筹学的算法，用matlab实现， matlab for OR one by one (matlab for OR)

Gardner算法的Matlab仿真与实现(simulation and implementation of Gardner algorithm)
