torch.imag — PyTorch 2.7 documentation (original) (raw)
Shortcuts
Returns a new tensor containing imaginary values of the self
tensor. The returned tensor and self
share the same underlying storage.
Warning
imag() is only supported for tensors with complex dtypes.
Parameters
input (Tensor) – the input tensor.
Example:
x=torch.randn(4, dtype=torch.cfloat) x tensor([(0.3100+0.3553j), (-0.5445-0.7896j), (-1.6492-0.0633j), (-0.0638-0.8119j)]) x.imag tensor([ 0.3553, -0.7896, -0.0633, -0.8119])
