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

SYNOPSIS
       SUBROUTINE DLAMRG( N1, N2, A, DTRD1, DTRD2, INDEX )

	   INTEGER	  DTRD1, DTRD2, N1, N2

	   INTEGER	  INDEX( * )

	   DOUBLE	  PRECISION A( * )

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.

ARGUMENTS
       N1     (input) INTEGER
	      N2     (input) INTEGER These arguements contain the respective lengths of the two sorted lists to be merged.

       A      (input) 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  (input) INTEGER
	      DTRD2  (input) 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  (output) 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 ascend-
	      ing order.
