tf.angle

tf.angle(
    input,
    name=None
)

Defined in tensorflow/python/ops/math_ops.py.

See the guide: Math > Complex Number Functions

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

Given a tensor input, this operation returns a tensor of type float that is the argument of each element in input 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:

# tensor 'input' is [-2.25 + 4.75j, 3.25 + 5.75j]
tf.angle(input) ==> [2.0132, 1.056]

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.
