(e.g. when I write Ket[\psi] and call a function, there is no problem, but when I try to input in the bra-ket notation like |psi> using aliases defined here, it gives errors like > > Syntax::sntxi: Incomplete expression; more input is needed > > ) > > Nevertheless, I have succesfully come to In[56], but the inputs after [56] are troublesome.
