Dormand-Prince method (variable step size) 5th order method with 4th order error estimate

RK23

Bogacki-Shampine method (variable step size) 3rd order method with 2nd order error estimate

Bdf

Backward Differentiation Formula (BDF) method Implicit method for stiff equations Default is BDF order 2

Dormand-Prince method of order 8(5,3) 8th order method with 5th order error estimate High-accuracy explicit Runge-Kutta method

Radau

Implicit Runge-Kutta method of Radau IIA family 5th order method with 3rd order error estimate L-stable implicit method for stiff problems

LSODA

Livermore Solver for Ordinary Differential Equations with Automatic method switching Automatically switches between Adams methods (non-stiff) and BDF (stiff) Efficiently handles problems that change character during integration

EnhancedLSODA

Enhanced LSODA method with improved stiffness detection and method switching Features better Jacobian handling, adaptive order selection, and robust error control Provides detailed diagnostics about method switching decisions

EnhancedBDF

Enhanced BDF method with improved Jacobian handling and error estimation Features intelligent Jacobian strategy selection based on problem size Supports multiple Newton solver variants and provides better convergence Includes specialized handling for banded matrices and adaptive order selection

Trait Implementations

impl Clone for ODEMethod

fn clone(&self) -> ODEMethod

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ODEMethod

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ODEMethod

fn default() -> ODEMethod

Returns the “default value” for a type.

impl PartialEq for ODEMethod

fn eq(&self, other: &ODEMethod) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
