State indexing question

[faq_user]

I am looking for the easiest way to convert the (L,M) index the "stateinfo" function generates to maybe Hilbert space matrix representation in the end. I would like to know if you have any suggestions on how to do that. Right now I am looking through the stateinfo function to see how you did the index conversion from 0,1,2,3 to (L,M).

See the lin2lm and lm2lin functions in kernel utilities. The operator and state functions also support direct tensor index specification, such as ‘T2,-2’ in the operator description.

To get Hilbert space operators, switch bas.formalism to ‘zeeman-hilb’.
