Arguments

Type IntentOptional Attributes Name
real(kind=real64), intent(in) :: p1(2)

Point 1.
real(kind=real64), intent(in) :: p2(2)

Point 2.
real(kind=real64), intent(in) :: p3(2)

Point 3.

Return Value real(kind=real64)

The angle swept out by the rays, in radians. If either ray has zero length, then the angle is set to 0.
