# tensorflow::ops::Polygamma Class Reference

# tensorflow::ops::Polygamma

`#include <math_ops.h>`

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

## Summary

The polygamma function is defined as:

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

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

Arguments:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object

<br />

Returns:

- `https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output`: The z tensor.
