LS_diffusion

该源码是一些代码程序，现上传上去望大家指正(The source code is a number of procedures is up hope you upload correction)

This code is about migration of seismic data.

本代码对OFDM中载波频偏对系统误码率的影响进行了全面的仿真和比较，对加深对OFDM载波同步技术的理解很有帮助(The code in OFDM carrier frequency offset the impact of the system bit error rate of a comprehensive simulation and comparison to deepen the understanding of OFDM carrier synchronization helpful)

这是中国数学建模中编程交流上贪婪算法内容，里面提供了很多贪婪算法的例子(This is the exchange of mathematical modeling in the programming content on the greedy algorithm, which provides many examples of greedy algorithm)

说明：  基于MATLAB遗传算法(SGA)实现 基于MATLAB遗传算法(SGA)实现(MATLAB based genetic algorithm (SGA) based on MATLAB genetic algorithm (SGA) to achieve)

模糊c均值聚类的一种改进算法，比较简单。用的时候先初始化一下，在不断迭代，参考里面的main函数吧。参考的时候去掉一些无关的命令，有些命令是我自己调用的无关的命令，可能目录里面没有，但不妨碍这个算法运行，可以屏蔽掉。(an improved fuzzy c means clustering algorithm)

线性规划 包括单纯形法，梯度，牛顿(linear programming including the simplex method, gradient, Newton, etc.)

matlab编写的文本分类的程序，可以对已经分好词的文本进行分类，先自己导入数据，用libsvm中的svm进行分类和预测，特征用tfidf算法，还利用卡方检验进行了特征选择，可自行设定阈值。(matlab prepared text classification program, you can have a good word of text classification, classification and prediction using libsvm in svm, characterized by tfidf algorithm, also used the chi-square test was used for feature selection, you can set thresholds on their own.)

三次样条插值函数的三弯矩法，精度较高，值得一看(Cubic spline interpolation function of the three moment method, high accuracy, see)

matlab方面有很多程序可以使用到学习与工作中(matlab, there are many programs you can use to learn and work)
