SYNOPSIS
Functions/Subroutines
subroutine dlasrt (ID, N, D, INFO)
DLASRT
Function/Subroutine Documentation
subroutine dlasrt (characterID, integerN, double precision, dimension( * )D, integerINFO)
DLASRT
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
