conatus.expert.floquet_exponents(build, base_harmonics, kx, kz, *, method, fields, period=1.0, **kw)

Floquet exponents of the wave (kx, kz) with the same build and base_harmonics as optimal_gain(). method="hill" (Nh, targets: shift-invert Arnoldi on the μ-linear Hill pencil, exponents nearest each target, residual-filtered at residual_max) or "monodromy" (steps, scheme: eigenvalues of the discrete monodromy matrix on the admissible states). fields only defines the state (energy is not used).

Parameters:

• build (Callable[[Mapping[str, float]], Any])

• base_harmonics (Mapping[Any, Mapping[int, Any]])

• kx (float)

• kz (float)

• method (str)

• period (float)

Return type:
