Struct AnomalousDiffusionParams 

pub struct AnomalousDiffusionParams {
    pub alpha: f64,
    pub diffusivity: f64,
}

Parameters for an anomalous diffusion model.

Subdiffusion: 0 < α < 1, mean-squared displacement ⟨x²⟩ ~ t^α. Normal diffusion: α = 1, ⟨x²⟩ ~ t. Superdiffusion: 1 < α < 2, ⟨x²⟩ ~ t^α.

Fields

alpha: f64

Fractional order α ∈ (0, 2).

diffusivity: f64

Generalized diffusion coefficient K_α [m² s^{-α}].

Implementations

impl AnomalousDiffusionParams

pub fn new(alpha: f64, diffusivity: f64) -> Self

Create new anomalous diffusion parameters.

pub fn msd(&self, t: f64) -> f64

Mean squared displacement at time t: ⟨x²⟩(t) = 2 K_α t^α / Γ(1+α).

pub fn anomalous_exponent(&self) -> f64

Diffusion exponent (anomalous scaling exponent).

pub fn is_subdiffusion(&self) -> bool

Check if the process is subdiffusive.

pub fn is_superdiffusion(&self) -> bool

Check if the process is superdiffusive.
