entr
(x) = <ufunc 'entr'>¶ Elementwise function for computing entropy.
\[\begin{split}\text{entr}(x) = \begin{cases} - x \log(x) & x > 0 \\ 0 & x = 0 \\ -\infty & \text{otherwise} \end{cases}\end{split}\]- Parameters
- xndarray
Input array.
- Returns
- resndarray
The value of the elementwise entropy function at the given points x.
Notes
This function is concave.
