Python | Sympy line.are_concurrent 方法
原文:https://www.geesforgeks.org/python-sympy-line-are_concurrent-method/
In Sympy, the function are_concurrent() is used to check whether the given linearentities(lines) are concurrent or not. Two or more linear entities are concurrent ifthey all intersect at a single point.
Syntax: Line.are_concurrent(lines)
Parameters:
lines: a sequence of linear entities.
Returns:
True: if the set of linear entities intersect in one point
False: otherwise.
示例#1:
# import sympy and Point, Line
from sympy import Point, Line
p1, p2 = Point(0, 0), Point(3, 5)
p3, p4 = Point(-2, -2), Point(0, 2)
l1, l2, l3 = Line(p1, p2), Line(p1, p3), Line(p1, p4)
# using are_concurrent() method
areConcurrent = Line.are_concurrent(l1, l2, l3)
print(areConcurrent)
输出:
True
示例#2:
# import sympy and Point, Line
from sympy import Point, Line
p1, p2 = Point(0, 0), Point(3, 5)
p3, p4 = Point(-2, -2), Point(0, 2)
l1, l2, l3 = Line(p1, p3), Line(p1, p4), Line(p2, p3)
# using are_concurrent() method
areConcurrent = Line.are_concurrent(l1, l2, l3)
print(areConcurrent)
输出:
False
