利用两点距离计算经纬度的matlab程序，欢迎交流。-use latitude and longitude distance calculation procedures of Matlab, welcomed the exchange.

采用序列化对象CArchive读入原始数据构建Delaunay三角网的VC++代码。可以鼠标点击加新点进行构网，包括二维、三维。还可以进行设色、光照等。-Serializing objects using CArchive read the raw data to build Delaunay triangulation VC++ Code. Mouse clicks can add new points structure network, including the two-dimensional, three-dimensional. Can also be used for colors, light and so on.

该文件代码是基于ARCGIS的二次开发，里面实现了缓冲区分析，前提是需要安装ARCGIS二次开发工具包，所以，需要使用的可以从这里下载，试用。c#该源码实现了GIS中点、线、面的缓冲区分析。有距离缓冲区、属性值缓冲区和分级缓冲区三种。

这是老师布置的工程实践的作业， 有很好的参考价值， 代码都有注释。值得分享。

原题：编写一个子程序NewTon（float x0，float eps，float x1）。它的功能是用牛顿迭代法求f（x）=x*x*x-2x*x+4x+1在x=0附近的一个实根。若迭代成功，则返回费0值；否则，返回0。-original title : the preparation of a subroutine NewTon (x0 float, float eps, float x1). Its function is to use Newton"s iterative method for f (x) = x* x* x-2x 4x* x 1 x = 0 in the vicinity of a real roots. If successful iteration, the returned value fees 0; Otherwise, the return 0.

李学武提交的C语言源代码，包括Hilbert曲线，高精度计算，π值计算公式，取石子游戏，趣味等式填数游戏3则，验证四色定理等- Li Xuewu submits the C language source code, including the Hilbert curve, the high accuracy computation, pi the value formula, takes the gravel game, the interest equality fills in the number to play 3 pieces, confirms four colors theorems and so on

用CORDIC算法实现的2参数反正切。结果的精度与CORDIC的迭代次数有关，迭代次数越多，精度越高。本例子中精确到小数点后4位。要提高迭代次数，还得把增加1QN格式的位数，比如32位long，程序多处需要修改，有需要的话自己改吧。 -CORDIC algorithm with the two parameters arc tangent. And the accuracy of the CORDIC iteration number, the more the number of iteration, the higher the accuracy. This case accurate to four decimal places. To raise the number of iterations, it has to the increase in a 2:30 format of the median, such as 32 long, multiple procedures need to change, the need to reform it themselves.
