[tex] |\alpha \rangle = c \sum_{n=0}^\infty \frac{\alpha^n}{\sqrt{n!}} | n\rangle [/tex]

where

[tex] |n\rangle = \frac{(a^\dagger)^n}{\sqrt{n!}} |0\rangle [/tex]

and |0> is called the initial state.

I've some code where I need to have this initial state for j=4, so it should be a 9 by 1 vector right?

How is this initial state found?
