NAME
SLASRT - the number in D in increasing order (if ID = aqIaq) or in decreasing order (if ID = aqDaq )
SYNOPSIS
- SUBROUTINE SLASRT(
-
ID, N, D, INFO )
-
CHARACTER
ID
-
INTEGER
INFO, N
-
REAL
D( * )
PURPOSE
Sort the numbers in D in increasing order (if ID = aqIaq) or
in decreasing order (if ID = aqDaq ).
Use Quick Sort, reverting to Insertion sort on arrays of
size <= 20. Dimension of STACK limits N to about 2**32.
ARGUMENTS
- ID (input) CHARACTER*1
-
= aqIaq: sort D in increasing order;
= aqDaq: sort D in decreasing order.
- N (input) INTEGER
-
The length of the array D.
- D (input/output) 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 (output) INTEGER
-
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
