mindspore.ops.ComplexAbs

class mindspore.ops.ComplexAbs

Returns a Tensor that contains the magnitudes of the input.

The complex numbers in input must be of the form $a+bj$, where $a$ is the real part and $b$ is the imaginary part.

$$y=\sqrt{a^2+b^2}$$

Warning

This is an experimental API that is subject to change or deletion.

Inputs:

• x (Tensor) - A Tensor, types: complex64, complex128.

Outputs:

Tensor, has the same shape as x. If the type of x is complex64, the type of output is float32. If the type of x is complex128, the type of output is float64.

Raises

• TypeError – If the input is not a Tensor.

• TypeError – If the input type is not complex64 or complex128.

Supported Platforms:

Ascend GPU CPU

Examples

>>> import mindspore
>>> import numpy as np
>>> from mindspore import Tensor, ops
>>> x = Tensor(np.asarray(np.complex(3+4j)), mindspore.complex64)
>>> complex_abs = ops.ComplexAbs()
>>> output = complex_abs(x)
>>> print(output)
