  • Implements the Ogita-Aishima iteration method in a more robust way without scipy's ode solvers.
  • Set ogita-aishima as a default option.
  • Update notebooks/large_matrix_tracking_demo.ipynb to use ogita-aishima.

[P1] Restore positional argument compatibility

The signature now lists solver_method before correction_method, whereas the previous release exposed the opposite order. Any existing call that passed these optional arguments positionally (e.g. eigenpairtrack(..., "matching", "RK45")) will now treat the correction value as the solver method and vice versa, typically resulting in invalid method names being forwarded to solve_ivp or correct_trajectory. Unless positional arguments are explicitly unsupported, this is a backwards‑incompatible change that will break working client code. Consider keeping the original parameter order or enforcing keyword‑only parameters to avoid silent API breakage.
