tensorflow::ops::Polygamma

Compute the polygamma function \(\psi^{(n)}(x)\).

Summary

The polygamma function is defined as:

\(\psi^{(a)}(x) = \frac{d^a}{dx^a} \psi(x)\)

where \(\psi(x)\) is the digamma function. The polygamma function is defined only for non-negative integer orders \

Args:

• scope: A Scope object

Returns:

• Output: The z tensor.
