Struct SymplecticMatrix 

pub struct SymplecticMatrix {
    pub entries: Vec<Vec<f64>>,
    pub dim: usize,
}

A 2n×2n symplectic matrix M satisfying MᵀΩM = Ω.

Fields

entries: Vec<Vec<f64>>

Matrix entries (row-major)

dim: usize

Half the matrix dimension (matrix is 2n×2n)

Implementations

impl SymplecticMatrix

pub fn new(dim: usize) -> Self

Create the 2n×2n standard symplectic identity matrix J = [[0, Iₙ], [-Iₙ, 0]].

pub fn is_symplectic(&self) -> bool

Check whether this matrix is symplectic: MᵀΩM = Ω. For the canonical J itself this is always true.

pub fn determinant(&self) -> f64

Determinant of the symplectic matrix. For Sp(2n) matrices det = 1.
