NAME
       SRC/dlamrg.f

SYNOPSIS
   Functions/Subroutines
       subroutine dlamrg (n1, n2, a, dtrd1, dtrd2, index)
           DLAMRG creates a permutation list to merge the entries of two
           independently sorted sets into a single set sorted in ascending
           order.

Function/Subroutine Documentation
   subroutine dlamrg (integer n1, integer n2, double precision, dimension( * )
       a, integer dtrd1, integer dtrd2, integer, dimension( * ) index)
       DLAMRG creates a permutation list to merge the entries of two
       independently sorted sets into a single set sorted in ascending order.

       Purpose:


            DLAMRG will create a permutation list which will merge the elements
            of A (which is composed of two independently sorted sets) into a
            single set which is sorted in ascending order.

       Parameters
           N1

                     N1 is INTEGER

           N2

                     N2 is INTEGER
                    These arguments contain the respective lengths of the two
                    sorted lists to be merged.

           A

                     A is DOUBLE PRECISION array, dimension (N1+N2)
                    The first N1 elements of A contain a list of numbers which
                    are sorted in either ascending or descending order.  Likewise
                    for the final N2 elements.

           DTRD1

                     DTRD1 is INTEGER

           DTRD2

                     DTRD2 is INTEGER
                    These are the strides to be taken through the array A.
                    Allowable strides are 1 and -1.  They indicate whether a
                    subset of A is sorted in ascending (DTRDx = 1) or descending
                    (DTRDx = -1) order.

           INDEX

                     INDEX is INTEGER array, dimension (N1+N2)
                    On exit this array will contain a permutation such that
                    if B( I ) = A( INDEX( I ) ) for I=1,N1+N2, then B will be
                    sorted in ascending order.
