tensorflow.math.atan2() function in Python

TensorFlow is open-source python library designed by Google to develop Machine Learning models and deep learning  neural networks. atan2() is used to find element wise arctangent of y/x.

Syntax: tf.math.atan2(y, x, name)

Parameters: 

  • y: It’s the input tensor. Allowed dtype for this tensor are bfloat16, half, float32, float64. 
  • y: It’s the input tensor of same dtype as y.
  • name(optional): It’s defines the name for the operation.
     

Returns:  It returns a tensor of same dtype as x.

# importing the library
import tensorflow as tf
  
# Initializing the input tensor
a = tf.constant([ [-5, -7], [ 2, 0]], dtype = tf.float64)
b = tf.constant([ [1, 3], [9, 4]], dtype = tf.float64)
  
# Printing the input tensor
print('a: ', a)
print('b: ', b)
  
# Calculating result
res = tf.math.atan2(a, b)
  
# Printing the result
print('Result: ', res)

Output:

a:  tf.Tensor(
[[-5. -7.]
 [ 2.  0.]], shape=(2, 2), dtype=float64)
b:  tf.Tensor(
[[1. 3.]
 [9. 4.]], shape=(2, 2), dtype=float64)
Result:  tf.Tensor(
[[-1.37340077 -1.16590454]
 [ 0.21866895  0.        ]], shape=(2, 2), dtype=float64)

Result: tf.Tensor([-0.46364761 -0.14888995 0. 0.07485985 0.09966865], shape=(5, ), dtype=float64)
