NAME
       lasrt - lasrt: sort vector

SYNOPSIS
   Functions
       subroutine dlasrt (id, n, d, info)
           DLASRT sorts numbers in increasing or decreasing order.
       subroutine slasrt (id, n, d, info)
           SLASRT sorts numbers in increasing or decreasing order.

Detailed Description
Function Documentation
   subroutine dlasrt (character id, integer n, double precision, dimension( *
       ) d, integer info)
       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
           !>
