Hello all,
Consider the following code:
from sympy import *
from sympy.physics.secondquant import KroneckerDelta
from sympy.tensor import IndexedBase, Idx
from sympy.functions import conjugate
init_printing()
Psi = Symbol('Psi_0', complex=True, real=False)
print(Psi.is_real)
print(Psi.is_complex)
print(latex(Psi * conjugate(Psi)))
Psi = IndexedBase(Symbol('Psi', complex=True, real=False))
print(Psi[0].is_real)
print(Psi[0].is_complex)
print(latex(Psi[0] * conjugate(Psi[0])))
Its output is
False
True
\Psi_{0} \overline{\Psi_{0}}
False
False
Psi[0] \overline{Psi[0]}
This raises two questions:
1) What is the proper way of setting constraints for indexed objects?
2) How do I make indexes and symbols get pretty printed in the same way as
for the normal symbols (i.e. using subscripts and greek letter where
appropriate)? Do I have to write a custom printer function?
