Symplectic Euler methods

This module provides first-order symplectic integrators known as Symplectic Euler methods. These are the simplest symplectic integrators and come in two variants:

• Symplectic Euler A (position first): Updates position first, then momentum
• Symplectic Euler B (momentum first): Updates momentum first, then position

While first-order, these methods exactly conserve the symplectic structure and provide bounded energy error over long integration times.

Structs

SymplecticEulerA

Symplectic Euler Method A - updates position first, then momentum

SymplecticEulerB

Symplectic Euler Method B - updates momentum first, then position
