三角形判断问题。可用于黑盒测试用例设计。(Triangle judgment. Can be used for black-box test case design.)

这是pscad运行的电弧炉模型，是学习pscad很好的例子(This is pscad running electric arc furnace model, is learning pscad good example)

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)

该程序是用C 语言编写的图形学中的贝济尔曲线,简单实用易懂(this program is Bezier program about computer picture,wich is degn by c.)

等值线函数.// As this code is ported from FORTRAN-77, please be very careful of the // various indices like ilb,iub,jlb and jub, remeber that C/C++ indices // starts from zero (0)(contour function.// As this code is ported from FORTRAN-77, please be very careful of the// various indices like ilb, iub, and* address, remember that the C/C indices// starts from zero (0))

实用三百例 前后学习 融会贯通 而且每个实例都是一个小模块 从画图到计算(Around three hundred cases of practical mastery learning and each instance is a small module from the drawing to the calculation)

PSCAD做的12模块H桥SVG模型，电流矢量控制，运行良好。(PSCAD do SVG module 12 H bridge model, the current vector control, work well.)

对角度跟踪并给出详细的跟踪结果，比较不同情况下的运行效率，绘制跟踪误差曲线，直接给出曲线图，可以直接运行.(For pure Angle tracking and give detailed tracking results, draw tracking error curve, compare different situations efficiency, direct given curve, can be directly run)

社区发现最常用的画图工具netdraw 使用简单方便 里面有使用说明 及例子 直接导入里面的例子文件即可(netdraw community detection)
