Python Sympy Line.distance()用法及代码示例


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
