NAME

       dlasrt.f -

SYNOPSIS

   Functions/Subroutines
       subroutine dlasrt (ID, N, D, INFO)
	   DLASRT sorts numbers in increasing or decreasing order.

Function/Subroutine Documentation
   subroutine dlasrt (characterID, integerN, double precision, dimension( * )D, integerINFO)
       DLASRT sorts numbers in increasing or decreasing order.

       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.

       Parameters:
	   ID

		     ID is CHARACTER*1
		     = 'I': sort D in increasing order;
		     = 'D': sort D in decreasing order.

	   N

		     N is INTEGER
		     The length of the array D.

	   D

		     D is 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

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