Function/Subroutine Documentation
subroutine slasrt (character id, integer n, real, dimension( * ) d, integer info)
SLASRT 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 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
!> INFO is INTEGER !> = 0: successful exit !> < 0: if INFO = -i, the i-th argument had an illegal value !>
