jax.numpy.conjugate

jax.numpy.conjugate(x)

Return the complex conjugate, element-wise.

LAX-backend implementation of conjugate(). Original docstring below.

conjugate(x, /, out=None, *, where=True, casting=’same_kind’, order=’K’, dtype=None, subok=True[, signature, extobj])

The complex conjugate of a complex number is obtained by changing the sign of its imaginary part.

Parameters

x (array_like) – Input value.

Returns

y – The complex conjugate of x, with same dtype as y. This is a scalar if x is a scalar.

Return type

ndarray

Notes

conj is an alias for conjugate:

>>> np.conj is np.conjugate
True

Examples

>>> np.conjugate(1+2j)
(1-2j)

>>> x = np.eye(2) + 1j * np.eye(2)
>>> np.conjugate(x)
array([[ 1.-1.j,  0.-0.j],
       [ 0.-0.j,  1.-1.j]])
