针对光学二次谐波系统的全局耦合网络同步，迭代并画出相图(For optical second harmonic system, iteration and phase diagram are drawn.)

有100个数据点,知道x,y,z的坐标,用命令把这些点拟合成空间的曲线?看点的分布应该是螺旋线,得出一个表达式来表达曲线,有程序(Has 100 data points, know that x, y, z coordinates, using the order of these points to be synthetic curve space? Highlight the distribution should be a spiral line, derived an expression to express the curve, the procedure has)

一个简单的程序，可以绘制点、线、圆、方。可以保存成一定格式的图片文件。软件最大的问题是绘图基本在对应的鼠标事件里进行，而没有在paint方法里进行，可借鉴。(A simple program, you can draw points, lines, circles, square. Can be saved into a certain format image files. The biggest problem is the graphics software basic mouse events in the corresponding conduct, but not in the paint method in the conduct, we may learn.)
