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
