square in PyTorch

*Memos:

• My post explains pow().
• My post explains float_power().
• My post explains abs() and sqrt().
• My post explains gcd() and lcm().
• My post explains trace(), reciprocal() and rsqrt().

square() can get the 0D or more D tensor of squared zero or more elements, getting the 0D or more D tensor of zero or more elements as shown below:

*Memos:

• square() can be used with torch or a tensor.
• The 1st argument(input) with torch or using a tensor(Required-Type:tensor of int, float, complex or bool).
• There is out argument with torch(Optional-Default:None-Type:tensor): *Memos:
  • out= must be used.
  • My post explains out argument.

import torch

my_tensor = torch.tensor(-3)

torch.square(input=my_tensor)
my_tensor.square()
# tensor(9)

my_tensor = torch.tensor([-3, 1, -2, 3, 5, -5, 0, -4])

torch.square(input=my_tensor)
# tensor([9, 1, 4, 9, 25, 25, 0, 16])

my_tensor = torch.tensor([[-3, 1, -2, 3],
                          [5, -5, 0, -4]])
torch.square(input=my_tensor)
# tensor([[9, 1, 4, 9],
#         [25, 25, 0, 16]])

my_tensor = torch.tensor([[[-3, 1], [-2, 3]],
                          [[5, -5], [0, -4]]])
torch.square(input=my_tensor)
# tensor([[[9, 1], [4, 9]],
#         [[25, 25], [0, 16]]])

my_tensor = torch.tensor([[[-3., 1.], [-2., 3.]],
                          [[5., -5.], [0., -4.]]])
torch.square(input=my_tensor)
# tensor([[[9., 1.], [4., 9.]],
#         [[25., 25.], [0., 16.]]])

my_tensor = torch.tensor([[[-3.+0.j, 1.+0.j], [-2.+0.j, 3.+0.j]],
                          [[5.+0.j, -5.+0.j], [0.+0.j, -4.+0.j]]])
torch.square(input=my_tensor)
# tensor([[[9.-0.j, 1.+0.j], [4.-0.j, 9.+0.j]],
#         [[25.+0.j, 25.-0.j], [0.+0.j, 16.-0.j]]])

my_tensor = torch.tensor([[[True, False], [True, False]],
                          [[False, True], [False, True]]])
torch.square(input=my_tensor)
# tensor([[[1, 0], [1, 0]],
#         [[0, 1], [0, 1]]])
