Python – tensorflow.math.igammac()

Last Updated : 17 Jun, 2021

TensorFlow is open-source Python library designed by Google to develop Machine Learning models and deep learning neural networks.

igammac() is used to Compute the upper regularized incomplete Gamma function Q(a, x). Q(a, x) is defined as:

where gamma(a, x) is the lower incomplete Gamma function and is defined as:

Syntax: tensorflow.math.igammac( x, y, name)

Parameters:

x: It is a tensor. Allowed dtypes are float32, float64.

y: It is a tensor of same dtype as x.

name(optional): It defines the name of the operation

Returns: It returns a tensor of dtype as x.

Example 1:

Python3

# importing the library
import tensorflow as tf
 
# Initializing the input tensor
a = tf.constant([7, 8, 13, 11], dtype = tf.float64)
b = tf.constant([2, 8, 14, 5],  dtype = tf.float64)
 
# Printing the input tensor
print('a: ', a)
print('b: ', b)
 
# Calculating the result
res = tf.math.igammac(a, b)
 
# Printing the result
print('Result: ', res)

Output:

a:  tf.Tensor([ 7.  8. 13. 11.], shape=(4, ), dtype=float64)
b:  tf.Tensor([ 2.  8. 14.  5.], shape=(4, ), dtype=float64)
Result:  tf.Tensor([0.99546619 0.45296081 0.35845842 0.98630473], shape=(4, ), dtype=float64)

Example 2:

Python3

# Importing the library
import tensorflow as tf
 
# Initializing the input tensor
a = tf.constant([2, 8, 14, 5], dtype = tf.float32)
b = tf.constant([7, 8, 13, 11],  dtype = tf.float32)
 
# Printing the input tensor
print('a: ', a)
print('b: ', b)
 
# Calculating the result
res = tf.math.igammac(a, b)
 
# Printing the result
print('Result: ', res)

Output:

a:  tf.Tensor([ 2.  8. 14.  5.], shape=(4, ), dtype=float32)
b:  tf.Tensor([ 7.  8. 13. 11.], shape=(4, ), dtype=float32)
Result:  tf.Tensor([0.00729505 0.45296064 0.57304585 0.0151046 ], shape=(4, ), dtype=float32)
