最小二乘曲线拟合圆，vc的源代码和推导过程(Least squares curve fitting circle, vc source code and derivation)

说明：  在大型机上使用NCL画WRF模式运转结果的雨量图(Use NCL to draw rainfall map of WRF mode operation result)

这个程序是用Breseham画法在visual c++平台下画直线和圆。可以对图像进行刷新，画多条直线，多个圆(This procedure is used Breseham paint in visual c++ platform for the next drawing a straight line and circle. Can refresh the image, painted more than a straight line, a number of round)

draw用法。新手必看，通俗易懂，请结合工具书(draw Xinshoubikan usage, easy to understand)

基于Bresenham算法的四步画直线算法,加快画直线速度(draw line based Bresenham update alogrith)

基于Bresenham算法的四步画直线算法,加快画直线速度(draw line based Bresenham update alogrith)

初学者常用的matlab绘图代码及讲解课件(Matlab drawing codes and instructional courseware commonly used by beginners)

说明：  上大学时候的一个习作，是模仿国外一个截图软件做的。它不但可以抓图，而且还可以选择抓图的形状，比如圆形、方形、三角形等。还有其它的一些辅助功能有很多(When one exercises in college, is an imitation of a screenshot of foreign software to do. It can not only drawings, but can also choose the shape of drawings, such as round, square, triangle and so on. There are some other auxiliary functions, many)

实现三角形的类、用类的继承关系编写程序描述下图1中的类层次(Write a class Triangle Triangle、Class inheritance relationships with programming description Figure 1 class hierarchy)

DDA方法的绘制直线 圆的绘制 曲线的绘制等(tu xing xue)
