SUBROUTINE DSORTilu (DX, IX, N, KFLAG, IERR)
C***BEGIN PROLOGUE DSORT
C***PURPOSE Sort an array and optionally make the same interchanges in
C an auxiliary array. The array may be sorted in increasing
C or decreasing order. A slightly modified QUICKSORT
C algorithm is used.
C***LIBRARY SLATEC
C***CATEGORY N6A2B
C***TYPE DOUBLE PRECISION (SSORT-S, DSORT-D, ISORT-I)
C***KEYWORDS SINGLETON QUICKSORT, SORT, SORTING
C***AUTHOR Jones, R. E., (SNLA)
C Wisniewski, J. A., (SNLA)
C***MODIFIED by K.Lipnikov (http://humpty.inm.ras.ru/~kos)
C***DESCRIPTION
C
C DSORT sorts array DX and optionally makes the same interchanges in
C array IX. The array DX may be sorted in increasing order or
C decreasing order. A slightly modified quicksort algorithm is used.
C
C Description of Parameters
C DX - array of values to be sorted (usually abscissas)
C IX - array to be (optionally) carried along
C N - number of values in array DX to be sorted
C KFLAG - control parameter
C = 2 means sort DX in increasing order and carry IX along.
C = 1 means sort DX in increasing order (ignoring IX)
C = -1 means sort DX in decreasing order (ignoring IX)
C = -2 means sort DX in decreasing order and carry IX along.
C
C IERR - the error's indicator
C = 0 - Okay
C != 0 - errors
