I propose the inclusion of a conj() function, as the numpy np.conj() function.
I have attempted it, but two errors show up (see at the end).
Grepping the code does not show any conjugate, but the numpy function conj
corresponds to the ufunc conjugate.
Find attached the output of
$ hg export tip > patch_conj
