PyTorch torch.adjoint() method “returns a view of the tensor conjugated and with the last two dimensions transposed.”
Syntax
torch.adjoint(Tensor)
Parameters
Tensor: It is an input tensor.
Example 1: Basic usage with a 2D complex tensor
import torch
tensor_1 = torch.tensor([[1 + 1j, 2 + 2j], [3 + 3j, 4 + 4j]])
adjoint_1 = torch.adjoint(tensor_1)
print("Original Tensor:")
print(tensor_1)
print("\nAdjoint Tensor:")
print(adjoint_1)
Output
Example 2: Using the method with higher-dimensional tensors
import torch
tensor_2 = torch.tensor([
[[1 + 1j, 2 + 2j], [3 + 3j, 4 + 4j]],
[[5 + 5j, 6 + 6j], [7 + 7j, 8 + 8j]]
])
adjoint_2 = torch.adjoint(tensor_2)
print("Original Tensor:")
print(tensor_2)
print("\nAdjoint Tensor:")
print(adjoint_2)
Output
Example 3: Using the method with real numbers
import torch
tensor_3 = torch.tensor([[1, 2], [3, 4]])
adjoint_3 = torch.adjoint(tensor_3)
print("Original Tensor:")
print(tensor_3)
print("\nAdjoint Tensor:")
print(adjoint_3)
Output
For real numbers, the adjoint is the same as the regular transpose since there’s no complex component to conjugate.
