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  Int32
(input) INTEGER
N2  Int32
(input) INTEGER These arguements contain the respective lengths of the two sorted lists to be merged.
A  Double
(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.
offset_a  Int32
 
DTRD1  Int32
(input) INTEGER
DTRD2  Int32
(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  Int32
(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 ascending order.
offset_index  Int32
