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
