    Elementwise function for computing entropy.
    .. math:: \text{entr}(x) = \begin{cases} - x \log(x) & x > 0  \\ 0 & x = 0 \\ -\infty & \text{otherwise} \end{cases}
    Parameters
    ----------
    x : Tensor
        Input tensor.
    Returns
    -------
    res : Tensor
        The value of the elementwise entropy function at the given points `x`.
