Struct Sindy 

pub struct Sindy {
    pub names: Vec<String>,
    pub coeffs: DMatrix<f64>,
}

A discovered model: the library term names and the sparse coefficient matrix Ξ (one column per state dimension).

Fields

names: Vec<String>

coeffs: DMatrix<f64>

coeffs[(term, dim)] — coefficient of library term in the equation for state component dim.

Implementations

impl Sindy

pub fn fit( states: &[Vec<f64>], derivs: &[Vec<f64>], degree: usize, lambda: f64, ) -> Sindy

Fit a sparse dynamics model. states[i] is the state at sample i; derivs[i] its time derivative. degree bounds the polynomial library; lambda is the sparsity threshold.

pub fn n_active(&self) -> usize

Number of nonzero terms across all equations.

pub fn equation(&self, dim: usize) -> String

Human-readable equation for state dimension dim, e.g. "ẋ = 1.00 y".
