"""
This layer takes an input and outputs a variable that has the same structure as
the input and with all the element values as zero. The variable can be a Tensor

.. code-block:: text
Given
X = [[0, 1, 2, 0],
[0, 3, 4, 0],
[0, 0, 0, 0]],
output is:
Out = [[0, 0, 0, 0],

Args:
x (Variable): The input variable, which could be a tensor or tensor array
Returns:
Variable: The zero-filled variable, which has the same type and shape as
the input variable.
Examples:
