Change the number of indices at the node by dragging the upper or lower side. This will cause the node to return the second, third, ... element or subarray (index 1, 2, ...).

			Specify an index at the '''index''' input terminal to start at a specific element from the array. The input terminals following after that are automatically incremented.

			For multidimensional arrays, the number of terminals for each element or subarray matches the number of dimensions of the source array.

Returns an element or subarray at a specific index from an n-dimensional array.

{{LabVIEW Palette Object Information|palette=Functions Palette/Programming/Array{{!}}Array palette|type=function}}

== Usage ==

If no index is specified, the function returns the first element or subarray as if the index was set to zero.

The index automatically increments if not specified. This also works with jumps, by defining the index of an element further below.

For n-dimensional arrays, the number of terminals for each element or subarray matches the number of dimensions of the source array.

The index terminals for n-dimensional arrays are sorted in descending order, with the top terminal for the highest dimension. The first four dimensions are given names. From the fifth dimension onwards, terminal names keep incrementing with the pattern "dim<n>", where "<n>" is the dimension number.
