# tf.math.angle

View source

Returns the element-wise argument of a complex (or real) tensor.

### Aliases:

• `tf.compat.v1.angle`
• `tf.compat.v1.math.angle`
• `tf.compat.v2.math.angle`
``````tf.math.angle(
input,
name=None
)
``````

Given a tensor `input`, this operation returns a tensor of type `float` that is the argument of each element in `input`免费成长做爱直播有哪些 considered as a complex number.

The elements in `input` are considered to be complex numbers of the form \(a + bj\), where a is the real part and b is the imaginary part. If `input` is real then b is zero by definition.

The argument returned by this function is of the form \(atan2(b, a)\). If `input` is real, a tensor of all zeros is returned.

#### For example:

``````input = tf.constant([-2.25 + 4.75j, 3.25 + 5.75j], dtype=tf.complex64)
tf.math.angle(input).numpy()
# ==> array([2.0131705, 1.056345 ], dtype=float32)
``````

#### Args:

• `input`: A `Tensor`. Must be one of the following types: `float`, `double`, `complex64`, `complex128`.
• `name`: A name for the operation (optional).

#### Returns:

A `Tensor` of type `float32` or `float64`.
