{{alias}}( x, i0, i1, i2 )
    Returns an element from a three-dimensional nested array.

    Negative indices are resolved relative to the last element along the
    respective dimension, with the last element corresponding to `-1`.

    If provided out-of-bounds indices, the function always returns `undefined`.

    Parameters
    ----------
    x: ArrayLikeObject
        Input nested array.

    i0: integer
        First dimension index.

    i1: integer
        Second dimension index.

    i2: integer
        Third dimension index.

    Returns
    -------
    out: any
        Element value.

    Examples
    --------
    > var x = [ [ [ 1, 2 ], [ 3, 4 ] ] ];
    > {{alias}}( x, 0, 0, 1 )
    2
