subroutinedlamrg(integern1,integern2,doubleprecision,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. ParametersN1 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.
