mappy_ds.root.LocalBfResult

class mappy_ds.root.LocalBfResult(success, y, eigvals, eigvecs, nfev, residual, message, params, theta)

Result of find_local_bf().

Attributes:

success, y, eigvals, eigvecs, nfev, message

As in CycleResult, at the bifurcation point.

residualnumpy.ndarray

Residual of the full system at the last iterate: \(T^n(y) - y\) followed by the real and imaginary parts of \(\det(DT^n(y) - e^{i\theta} I)\).

paramsdict or None

Parameters with the bifurcation parameter at its solved value, or None if the search failed.

thetafloat or None

Argument of the critical multiplier \(e^{i\theta}\), or None if the search failed.
