Returns the element or subarray of n-dimensional array at index.
Warning : A new tensor is created for the output.
array : class, n-dimensional tensor.
index : array, specifies a number that refers to a location within the input array. If you leave the index input unwired for a ND array, the Index Array function returns all elements of the array. If the index is equal to -1, this index is used to retrieve an array subnet rather than a single element. For example, to retrieve column 1 from a 2D array, the index must be equal to [-1, 1].
subarray : class, n-dimensional tensor indexed.
