# tf.math.conj

Returns the complex conjugate of a complex number.

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 $$a - bj$$.

# 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.
