PyTorch is an open-source machine learning library developed by Facebook. It is used for deep neural network and natural language processing purposes. The function torch.sinh() provides support for the hyperbolic sine function in PyTorch. It expects the input in radian form. The input type is tensor and if the input contains more than one element, element-wise hyperbolic sine is computed.
Syntax: torch.sinh(x, out=None) Parameters: x: Input tensor name (optional): Output tensor Return type: A tensor with the same type as that of x.
Code #1:

Python3

# Importing the PyTorch library
import torch
  
# A constant tensor of size 6
a = torch.FloatTensor([1.0, -0.5, 3.4, -2.1, 0.0, -6.5])
print(a)
  
# Applying the sinh function and
# storing the result in 'b'
b = torch.sinh(a)
print(b)

                    
Output:
 1.0000
-0.5000
 3.4000
-2.1000
 0.0000
-6.5000
[torch.FloatTensor of size 6]


   1.1752
  -0.5211
  14.9654
  -4.0219
   0.0000
-332.5700
[torch.FloatTensor of size 6]
  Code #2: Visualization

Python3

# Importing the PyTorch library
import torch
  
# Importing the NumPy library
import numpy as np
  
# Importing the matplotlib.pyplot function
import matplotlib.pyplot as plt
  
# A vector of size 15 with values from -5 to 5
a = np.linspace(-5, 5, 15)
  
# Applying the hyperbolic sine function and
# storing the result in 'b'
b = torch.sinh(torch.FloatTensor(a))
  
print(b)
  
# Plotting
plt.plot(a, b.numpy(), color = 'red', marker = "o"
plt.title("torch.sinh"
plt.xlabel("X"
plt.ylabel("Y"
  
plt.show()

                    
Output:
-74.2032
-36.3203
-17.7696
 -8.6771
 -4.2032
 -1.9665
 -0.7766
  0.0000
  0.7766
  1.9665
