At first sight, I'd propose to create an "o.a.c.m.complex.solvers" package where a "ComplexLaguerreSolver" would reside. However, I don't know what are the necessary and sufficient API methods that would define a "BaseUnivariateComplexSolver" interface that would be the counterpart of BaseUnivariateSolver<FUNC extends UnivariateFunction> (in package "o.a.c.m.analysis.solvers").
