tf.math.conj(
    x, name=None
)

Given a tensor input of complex numbers, this operation returns a tensor of complex numbers that are the complex conjugate of each element in 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.

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

For example:

tensor 'input' is [-2.25 + 4.75j, 3.25 + 5.75j]

tf.math.conj(input) ==> [-2.25 - 4.75j, 3.25 - 5.75j]

If x is real, it is returned unchanged.

Args:

x: Tensor to conjugate. Must have numeric or variant type.
name: A name for the operation (optional).

Returns:

A Tensor that is the conjugate of x (with the same type).

Raises:

TypeError: If x is not a numeric tensor.
