andIntervals

  interface andIntervals
    subroutine andIntervalsBothScalar(intervalA, intervalB, andedIntervals)
      type(IntervalT), intent(in) :: intervalA, intervalB
      type(IntervalT), pointer    :: andedIntervals(:)
    end subroutine andIntervalsBothScalar

    subroutine andIntervalsOneVector(intervalA, intervalsB, andedIntervals)
      type(IntervalT), intent(in) :: intervalA, intervalsB(:)
      type(IntervalT), pointer    :: andedIntervals(:)
    end subroutine andIntervalsOneVector

    subroutine andIntervalsBothVector(intervalsA, intervalsB, andedIntervals)
      type(IntervalT), intent(in) :: intervalsA(:), intervalsB(:)
      type(IntervalT), pointer    :: andedIntervals(:)
    end subroutine andIntervalsBothVector
  end interface

In all cases the intervals are first converted to RangeT structures as follows:

    range%lower%type  = INCLUSIVE
    range%upper%type  = EXCLUSIVE
    range%lower%value = interval%lower
    range%upper%value = interval%upper
  

In this form, they can be ANDed together by use of the dss_aux call andRangesPair (see section 9.5.6)

NOTE! This function requires the intervals to be well-formed (see section 17.1).
