Pure numpy中两条曲线的交点 从灵感matlab实现，写的如何检测两条曲线相交这个Python实现。 示例用法 from intersect import intersection a , b = 1 , 2 phi = np . linspace ( 3 , 10 , 100 ) x1 = a * phi - b * np . sin ( phi ) y1 = a - b * np . cos ( phi ) x2 = phi y2 = np . sin ( phi ) + 2 x , y = intersection ( x1 , y1 , x2 , y2 ) plt . plot ( x1 , y1 , c = "r" ) plt . plot ( x2 , y2 , c = "g" ) plt . plot ( x , y , "*k" ) plt . show () 安
