complex¶

paddle. complex ( real: paddle.Tensor, imag: paddle.Tensor, name: str | None = None ) → paddle.Tensor [source]

Return a complex tensor given the real and image component.

Parameters

real (Tensor) – The real component. The data type should be ‘float32’ or ‘float64’.
imag (Tensor) – The image component. The data type should be the same as real.
name (str|None, optional) – For details, please refer to Name. Generally, no setting is required. Default: None.

Returns

Tensor, The output tensor. The data type is ‘complex64’ or ‘complex128’, with the same precision as real and imag.

Note

paddle.complex supports broadcasting. If you want know more about broadcasting, please refer to Introduction to Tensor .

Examples

           >>> import paddle
>>> x = paddle.arange(2, dtype=paddle.float32).unsqueeze(-1)
>>> y = paddle.arange(3, dtype=paddle.float32)
>>> z = paddle.complex(x, y)
>>> print(z)
Tensor(shape=[2, 3], dtype=complex64, place=Place(cpu), stop_gradient=True,
[[0j    , 1j    , 2j    ],
 [(1+0j), (1+1j), (1+2j)]])
