slasrt: the number in D in increasing order (if ID = aqIaq) or in decreasing order (if ID = aqDaq )

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
