title: Creating an empty multidimensional array
body: <p>In Python when using <code>np.empty()</code>, for example <code>np.empty((3,1))</code> we get an array that is of size (3,1) but, in reality, it is not empty and it contains very small values (e.g., <code>1.7*(10^315)</code>). Is possible to create an array that is really empty/have no values but have given dimensions/shape?</p>
