对于数据结构每一章节的相应的练习题，巩固好数据结构(To consolidate data structure corresponding practice questions for each chapter of the data structure)

说明：  离散随机线性系统的卡尔曼滤波。 其中13lman.c是卡尔曼滤波函数，4rinv.c是滤波函数中用到的矩阵求逆函数，13lman0.c是主程序。(discrete stochastic linear Kalman filtering system. 13lman.c which is the Kalman filter function, 4rinv.c filtering function is used in the matrix inversion function, is the main program 13lman0.c.)

使用C语言建立带头结点链表实现了集合。并进行了性能上的优化。(Achieve set using C to build list witch head node. And make optimization in performance.)

画图法实验数据结构中二叉树先序、中序、后序遍历和显示。(Paint Method in the first order binary tree data structure, in order, post order traversal and display.)

关于中国邮递员的解决办法，个人觉得还不错的说(Chinese postman)

用链表解决约瑟夫问题。 约瑟夫环是一个数学的应用问题：已知n个人（以编号1，2，3...n分别表示）围坐在一张圆桌周围。从编号为k的人开始报数，数到m的那个人出列；他的下一个人又从1开始报数，数到m的那个人又出列；依此规律重复下去，直到圆桌周围的人全部出列。 其中包括一个实验报告，介绍了编程思路和输出结果截图。(List to resolve Joseph. Josephus is the application of a mathematical problem: Given n individuals (numbered 1, 2, 3, ... n, respectively) sitting around a round table around. From number k people began to count off the number to m the man out of the line his next person and from a number off, the man was out of the line number to m so regularly repeated down until roundtable around of the people all of the columns. Including a lab report describes the programming ideas and output screenshots.)

　广度优先搜索及深度优先搜索，用C语言实现，比较使用(Breadth-first search and depth first search, using C language, compared with)

用c/c++写的二叉排序树的插入与删除，有兴趣的朋友可以看一下(Insertions and deletions using c/c++ to write binary sort tree)

计算点到直线的距离．输入两点坐标确定一个直线，再输入一个点的坐标，计算该点到直线的距离．(Calculated point to the straight line distance. Enter the coordinates of two points determine a straight line, and then input the coordinates of a point, to calculate the straight-line distance between points.)

A*算法通过启发式探索下一结点，逐步逼近目标结点，且使得路径最短。(A* algorithm heuristic to explore the next node, and gradually approaching the target node, and that the shortest path.)
