dlamrg.f(3)							      LAPACK							       dlamrg.f(3)

NAME

       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 (integerN1, integerN2, double precision, dimension( * )A, integerDTRD1, integerDTRD2, 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 arguements 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.
