tf.compat.v1.raw_ops.Igamma

The lower regularized incomplete Gamma function is defined as:

P(a,x)=gamma(a,x)/Gamma(a)=1Q(a,x)

where

gamma(a,x)=intx0ta1exp(t)dt

is the lower incomplete Gamma function.

Note, above Q(a, x) (Igammac) is the upper regularized complete Gamma function.

a A Tensor. Must be one of the following types: bfloat16, half, 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.
