Compute the upper regularized incomplete Gamma function
`
Q(a, x)
`
.

## Summary


The upper regularized incomplete Gamma function is defined as:


\\(Q(a, x) = Gamma(a, x) / Gamma(a) = 1 - P(a, x)\\)


where


\\(Gamma(a, x) = int_{x}\^{} t\^{a-1} exp(-t) dt\\)


is the upper incomplete Gama function.


Note, above
`
P(a, x)
`
(
`
https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/ops/igamma#classtensorflow_1_1ops_1_1_igamma
`
) is the lower regularized complete Gamma function.


Args:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object

<br />


Returns:

- `
  https://www.tensorflow.org/versions/r2.5/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output
  ` : The z tensor.
