Detailed Description

Area of polygon.

Function for computing the area of a polygon (2D, convex or not). Function for computing the area of a polygon The polygon can be convex or not.

The method is only applicable for 2D polygons and points.

Example

polygon(:,1) = (/ 1.0_dp,2.0_dp,2.0_dp,1.0_dp /)
polygon(:,2) = (/ 1.0_dp,1.0_dp,2.0_dp,2.0_dp /)
 
area = areapoly( polygon )
 
! --> area = 1

See also example in test directory.
