Hi Sympy-users,

I'm trying to figure out if it's possible to evaluate an expression from 
the quantum physics module. I'm fairly new at Sympy but I have some python 
experience. I thought I would ask before I dived into the source code.

Say for example I have something like the code in 
examples/intermediate/coupled_cluster.py. It derives the energy and 
amplitude equations in second quantization, but it needs to be solved.

The energy equation after cleanup is here: 

E = AntiSymmetricTensor(f, (_k,), (_c,))*AntiSymmetricTensor(t, (_c,), 
(_k,)) + AntiSymmetricTensor(t, (_c,), (_l,))*AntiSymmetricTensor(t, (_d,), 
(_k,))*AntiSymmetricTensor(v, (_k, _l), (_d, _c))/2

Can I provide some values for AntiSymmetricTensor(t, (_c,), (_k,)) to be 
substituted with evalf or lambdify? 

Thanks in advance for your help!
Matt
