在Sympy中,该函数
distance()
用于查找给定线与给定点之间的最短距离。用法: Line.distance(other) 参数: other: a point 返回: shortest distance between a line and a point Raises: NotImplementedError is raised if `other` is not a Point
范例1:
# import sympy and Point, Line
from sympy import Point, Line
p1, p2 = Point(0, 0), Point(1, 1)
s = Line(p1, p2)
# using distance() method
shortestDistance = s.distance(Point(-1, 1))
print(shortestDistance)
输出:
sqrt(2)
范例2:
# import sympy and Point, Line
from sympy import Point, Line
p1, p2 = Point(0, 0, 0), Point(1, 1, 1)
s = Line(p1, p2)
# using distance() method
shortestDistance = s.distance(Point(-1, 1, 1))
print(shortestDistance)
输出:
2*sqrt(6)/3
