Structure coefficient tables for single transition operators.
Syntax
[pt_left,pt_right]=st_product_table(nlevels)
Arguments
nlevels - the number of energy levels in the system
Outputs
pt_left, pt_right - structure coefficients in the conventions:
S{n}*S{m}=...+pt_left(n,m,k)*S{k}+...
S{m}*S{n}=...+pt_right(n,m,k)*S{k}+...
corresponding to the expansion of the left and
right multiplicative action by S{n} on S{m}.
Numbering translation between single and double
indices is given by kq2lin.m and lin2kq.m
