tf.raw_ops.Polygamma

robots: noindex

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

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 \a\.

a A Tensor. Must be one of the following types: float32, float64.
x A Tensor. Must have the same type as a.
name A name for the operation (optional).

A Tensor. Has the same type as a.
