Subarray()

Extracts a number of elements from an array.

sub_array = Subarray(array my_array, integer start, integer count)

Argument	Contents
my_array	The input array
start	The position of the first element extracted
count	The number of elements extracted

An array containing the specified elements of my_array, or null, if start and count do not specify any elements.

If start is null, Subarray() extracts from the beginning of my_array.
If count is null, Subarray() returns all the elements of the array beginning with start.
Subarray() does not modify my_array; it creates a new array containing a subset of the elements.

array1 = {1, 2, {3, 4, 5}, {6, 7}, 8, 9}

sub = Subarray(array1, 4, 2)	// sub = {{6, 7}, 8}
x = Subarray(x, 1, 3)	// extracts the first three elements of x

Error Type	Meaning
Error	Start is less than one, or count is less than zero
