real¶

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

Returns a new Tensor containing real values of the input Tensor.

Parameters

• x (Tensor) – the input Tensor, its data type could be complex64 or complex128.

• name (str, optional) – The default value is None. Normally there is no need for user to set this property. For more information, please refer to Name .

Returns

a Tensor containing real values of the input Tensor.

Return type

Tensor

Examples

import paddle

x = paddle.to_tensor(
    [[1 + 6j, 2 + 5j, 3 + 4j], [4 + 3j, 5 + 2j, 6 + 1j]])
# Tensor(shape=[2, 3], dtype=complex64, place=CUDAPlace(0), stop_gradient=True,
#        [[(1+6j), (2+5j), (3+4j)],
#         [(4+3j), (5+2j), (6+1j)]])

real_res = paddle.real(x)
# Tensor(shape=[2, 3], dtype=float32, place=CUDAPlace(0), stop_gradient=True,
#        [[1., 2., 3.],
#         [4., 5., 6.]])

real_t = x.real()
# Tensor(shape=[2, 3], dtype=float32, place=CUDAPlace(0), stop_gradient=True,
#        [[1., 2., 3.],
#         [4., 5., 6.]])
