View inputs as arrays with at least three dimensions.

Parameters: a (ndarray) – Array.
Returns: An array with a.ndim >= 3. Copies are avoided where possible, and views with three or more dimensions are returned.

Arrays that already have three or more dimensions are preserved.
During backpropagation, this function propagates the gradient of the output array to the input arrays in a.
