SYNOPSIS

setxor(A,B, setOrder)

DESCRIPTION

Set exclusive OR of two arrays.
	C = setxor(A,B) returns the data of A and B that are not in their intersection (the symmetric difference), with no repetitions. That is, setxor(3f) returns the data that occurs in A or B, but not both. C is in sorted order.

OPTIONS

A	input array
B	input array
setOrder
	May be "sort" or "stable"

EXAMPLE

sample program:

   program demo_setxor
   use M_sets, only: setxor
   character(len=*),parameter :: g=’(*(g0,1x))’
   integer, allocatable      :: A(:)
   integer, allocatable      :: B(:)

      write(*,g) ’SETXOR’,’Find values of A and B not in their intersection.’
      A = [5,1,3,3,3]
      B = [4,1,2]
      write(*,g) ’A=’, A
      write(*,g) ’A=’, B
      write(*,g) setxor(A,B)
      write(*,g) setxor(A,B,’stable’)

   end program demo_setxor

Results:

 > SETXOR Find values of A and B not in their intersection.
 > A= 5 1 3 3 3
 > A= 4 1 2
 > 2 3 4 5
 > 5 3 4 2
