/**
* Initialize ndarray-like objects for representing zero-dimensional sub-array views of ancillary ndarray arguments.
*
* ## Notes
*
* -   This function ignores the first two ndarray-like objects, which are assumed to be the input and output ndarray, respectively.
* -   This function mutates the provided output array.
*
* @private
* @param {ArrayLikeObject<Object>} arrays - list of ndarray-like objects
* @param {Array<Object>} out - output array
* @returns {Array<Object>} output array
