对空间卫星、飞机等图像进行特征提取，提取的特征包括面积，周长，紧密度，及离心率(Space satellites, aircraft and other image feature extraction, the extracted features include area, perimeter, compactness, and eccentricity)

说明：  复杂网络研究与建模 总起来说这是一个关于矩阵的运算，用到了c语言里面的东西，实现一个矩阵的逆运算和矩阵的转置等，最终实现的是一个初始节点为4个节点的有向图，随即扩展为一个10000*10000的巨型矩阵，得到该有向图的图形， 与计算机图形学类似，该程序是在构建了一个算法后，用MATLAB实现了一个无标度网络的图形中的各个节点的概率密度，并根据各个节点的概率密度绘出该图 (将中文译成英语 And modeling complex networks Collectively this is a computation on the matrix, use the stuff inside c language to realize the inverse of a matrix and a matrix, etc., and ultimately is an initial node to four nodes directed graph, then Expands to a huge matrix 10000* 10000, by the digraphs graphics, And similar computer graphics, the program is built upon an algorithm, using MATLAB to achieve a scale-free network each node in the graph the probability density and probability density according to each node in the graph drawn )

Function to do PCA on an RGB image

使用matlab编写的经纬高、东北天数据和地心坐标数据之间的转换函数文件，包含了东北天坐标系的定义说明文件以及相关的转换公式。 三个函数的调用文件名：ECEFtoENV，ECEFtoLBH，LBHtoECEF。使用说明见函数的说明。(Prepared using matlab high latitude and longitude, northeast-day data and geocentric coordinate conversion functions between data file that contains the definition of the coordinate system Northeast day documentation and related conversion formulas. Three function calls filename: ECEFtoENV, ECEFtoLBH, LBHtoECEF. See the instructions for use function.)

Dissolve Gas Analysis

DFA算法。用matlab实现的DFA算法，不保证效率，只保证能运行。(DFA algorithm. DFA algorithm using matlab realize, does not guarantee efficiency, is only guaranteed to run.)

miller码的matlab(miller code matlab)

算术编码，matlab实现编码与译码，而且不考虑其精度(Arithmetic coding, matlab coding and decoding achieve, and do not take into account their accuracy)

abaqus中的动态分析方法,含有inp、for文件希望能给动态分析，提供点参考(Methods of dynamic analysis of abaqus, containing the inp, hope can give a dynamic analysis for file, provide a point of reference)

说明：  此为建模竞赛试题的一解决方案，题目及解题原理易见于普通建模辅导资料。程序使用图论模型完整解决了问题。(Modeling this as a test solution, the principle of easy questions and problem-solving counseling information modeling in general. Procedures for the use of graph theory model of a complete solution to the problem.)
