diameter

  

compute the diameter of points on a plane

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

diameter(g)

Parameters

g

-

list or set of points

Description

• 

The routine computes the diameter of a given set or list of points g. The output is a list of three elements where the first two elements are two points denoting the two endpoints of the diameter of g, the third element the distance between these two endpoints.

• 

To find the diameter of a list or set of points, the coordinates of the points must be numeric.

• 

The command with(geometry,diameter) allows the use of the abbreviated form of this command.

Examples

with(geometry):

point(A,0,0),point(B,2,0),point(C,1,3),point(F,1,6):

point(M,sqrt(2),3):

ps := [A, B, C, F, M]:

diameter(ps);

B,F,37
