The semantics are like python array slicing, though both limits
have to be specified: the output array contains the sequence of
elements in the input array from i0
(inclusive)
to i1
(exclusive). If a negative value is given
in either case, it is added to the length of the input array,
so that -1 indicates the last element of the input array.
The indices are capped at 0 and the input array length respectively,
so a large positive value may be used to indicate the end of the array.
If the end index is less than or equal to the start index,
a zero-length array is returned.
Note:
This documents the double-precision version of the routine.
Corresponding routines exist for other data types
(float
, long
, int
,
short
, byte
, String
,
Object
).
i0
and i1
slice(array(10,11,12,13), 0, 3) = [10, 11, 12]
slice(array(10,11,12,13), -2, 999) = [12, 13]
