Lm2lin.m

Converts L,M indexing of spin states into linear indexing. In the linear indexing convention, spin states are listed in the order of increasing L rank, and, within ranks, in the order of decreasing M projection. Zero base counting is used:

                 (L=0,M=0) -> I=0
                 (L=1,M=1) -> I=1
                 (L=1,M=0) -> I=2, et cetera...

Syntax

    I=lm2lin(L,M)

Parameters

    L   - ranks of the spin states

    M   - projections of the spin states

Outputs

    I   - linear indices of spin states, with
          I=0 corresponding to L=0, M=0.

Notes

See the state indexing section for further information about how Spinach enumerates spherical tensor states.
