SLASRT sorts numbers in increasing or decreasing order.

Function/Subroutine Documentation

subroutine slasrt (characterID, integerN, real, dimension( * )D, integerINFO)

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
