绘制庞加莱截面图,在相空间中适当(要有利于观察系统的运动特征和变化,如截面不能与轨线相切,更不能包含轨线)选取一截面,在此截面上某一对共轭变量如x1和x.1取固定值,称此截面为Poincare截面,相空间的连续轨迹与Poincare截面的交点成为截点。-mapping Poincare section, in phase space appropriate (observation system should be beneficial to the movement and change, i

该代码绝对本人原创,可根据两打直线的四个端点坐标求解交点,并判断交点为实交点或虚交点,若两直线重合或平行,则返回值为FALSE:
以下代码为求交点的函数,使用方法:
rtn=InterPointTwoLine(直线A起点X,直线A起点Y,直线A终点X,直线A终点Y,
直线B起点X,直线B起点Y,直线B终点X,直线B终点Y,
返回的交点X,返回的交点Y,交点类型)
有交点时该函数返回值为True,平行或重合时返回False
最后一个参数(Inter_Type)是
