SYNOPSIS

  Functions/Subroutines
subroutine slasrt (id, n, d, info)
SLASRT sorts numbers in increasing or decreasing order.

Function/Subroutine Documentation

  subroutine slasrt (character id, integer n, real, dimension( * ) d, integer info)

SLASRT 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 REAL 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
    !>
