Returns the complex conjugate of a complex number.

Given a tensor x of complex numbers, this operation returns a tensor of complex numbers that are the complex conjugate of each element in x. The complex numbers in x must be of the form \(a + bj\), where a is the real part and b is the imaginary part.

The complex conjugate returned by this operation is of the form \(a - bj\).

For example:

x = tf.constant([-2.25 + 4.75j, 3.25 + 5.75j])
<tf.Tensor: shape=(2,), dtype=complex128,
numpy=array([-2.25-4.75j,  3.25-5.75j])>

If x is real, it is returned unchanged.

For example:

x = tf.constant([-2.25, 3.25])
<tf.Tensor: shape=(2,), dtype=float32,
numpy=array([-2.25,  3.25], dtype=float32)>
