tf.imag

tf.imag(
    input,
    name=None
)

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

See the guide: Math > Complex Number Functions

Returns the imaginary part of a complex (or real) tensor.

Given a tensor input, this operation returns a tensor of type float that is the imaginary part of each element in input considered as a complex number. If input is real, a tensor of all zeros is returned.

For example:

x = tf.constant([-2.25 + 4.75j, 3.25 + 5.75j])
tf.imag(x)  # [4.75, 5.75]

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.
