complex¶

paddle. complex ( real, imag, name=None ) [source]

Return a compelx 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, optional) – For details, please refer to Name. Generally, no setting is required. Default: None.

Returns

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

Return type

Tensor

Note:

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

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)]])
