.atanh()

The .atanh() function in PyTorch calculates the inverse hyperbolic tangent for each value in a tensor.

Syntax

torch.atanh(input, *, out=None)

Parameters:

• input (Tensor): A tensor containing values strictly between -1 and 1 (exclusive).
• out (Tensor, optional): The output tensor to store the result. If not provided, a new tensor is created.

Return Value:

Returns a new tensor where each value is the inverse hyperbolic tangent of the corresponding value in input.

Example

The following example demonstrates the usage of the .atanh() function:

import torch

# Create a tensor
x = torch.tensor([0.5, -0.3, 0.0])

# Calculate the inverse hyperbolic tangent
y = torch.atanh(x)

# Print the result
print(y)
