"Witryna17 wrz 2024 · Newton's method yields It follows that the residual will eventually drop below the user's threshold. Moreover, if is large enough, then the routine will immediately exit "succesfully", because is small enough. Writing a robust nonlinear solver is a nontrivial exercise. You have to maintain a bracket around the root. " - Newton raphson residuals
