NAME
       DLASRT - the numbers in D in increasing order (if ID = 'I') or in decreasing order (if ID = 'D' )

SYNOPSIS
       SUBROUTINE DLASRT( ID, N, D, INFO )

	   CHARACTER	  ID

	   INTEGER	  INFO, N

	   DOUBLE	  PRECISION D( * )

PURPOSE
       Sort the numbers in D in increasing order (if ID = 'I') or in decreasing order (if ID = 'D' ).  Use Quick Sort, reverting to Insertion sort
       on arrays of
       size <= 20. Dimension of STACK limits N to about 2**32.

ARGUMENTS
       ID      (input) CHARACTER*1
	       = 'I': sort D in increasing order;
	       = 'D': sort D in decreasing order.

       N       (input) INTEGER
	       The length of the array D.

       D       (input/output) DOUBLE PRECISION array, dimension (N)
	       On entry, the array to be sorted.  On exit, D has been sorted into increasing order (D(1) <= ... <= D(N) ) or into decreasing order
	       (D(1) >= ... >= D(N) ), depending on ID.

       INFO    (output) INTEGER
	       = 0:  successful exit
	       < 0:  if INFO = -i, the i-th argument had an illegal value
