2014研究生数学建模竞赛A题及相关资料，供大家学习交流(2014 Graduate Mathematical Contest in Modeling A title and related information , for we learn )

logistic映射从倍周期分岔进入混沌的分岔图算法(Logistic mapping the period-doubling bifurcation into the bifurcation diagram of chaos algorithm)

feature extraction for genatic algorithm

这个算子算是图像历史上第一个特征点提取算法了，1977年提出的，很简单，拿来练手很合适。(This operator is the first feature point extraction algorithm in the history of the image. It was proposed in 1977. It is very simple and suitable for hand training.)

说明：  压缩感知算法，里面有大量压缩感知训练算法(AMP1235675432134564321)

对一篇文章中的文字进行比例分析并能求出出现频率最多的字。(Of an article in the proportion of text analysis and to derive a maximum frequency of occurrence of the word.)

说明：  使用直线段替换管道时的土壤温度场模拟，采用有限容积方法。(Replace the pipe using the straight line when the soil temperature field simulation, finite volume method.)

说明：  图像的huffman编解码程序，希望能给大家提供帮助(Huffman encoding and decoding process the image, hope that they can help)

光伏并网系统 三大服务而非我基于PI控制的电流内环控制 (PV grid system three services rather than my inner current loop control based on PI control)

二阶自抗扰控制器算法中跟踪微分器、扩张状态观测器和非线性误差反馈率的.m文件和simulink仿真图例。(Second-order tracking differentiator ADRC algorithm, the extended state observer and nonlinear error feedback rate. M file and simulink simulation legend.)
