Struct ELSolution 

pub struct ELSolution {
    pub lagrangian: LagrangianFunction,
    pub solution: String,
    pub is_extremal: bool,
}

Solution to the Euler-Lagrange equations for a given Lagrangian.

Fields

lagrangian: LagrangianFunction

The Lagrangian for which the E-L equations were solved.

solution: String

Description of the solution (extremal path).

is_extremal: bool

Whether this critical path is truly extremal.

Implementations

impl ELSolution

pub fn new() -> Self

Construct a default ELSolution for a 1-DOF system.

pub fn is_local_minimum(&self) -> bool

Returns true if the second variation is strictly positive (Legendre + Jacobi hold).

pub fn is_local_maximum(&self) -> bool

Returns true if the second variation is strictly negative.

pub fn is_saddle(&self) -> bool

Returns true if the extremal is a saddle point of the functional.
