NAME

SLASRT - the numbers in D in increasing order (if ID = ’I’) or in decreasing order (if ID = ’D’ )

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 = ’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.

ARGUMENTS

ID (input) CHARACTER*1

= ’I’: sort D in increasing order;
= ’D’: 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
