Struct FunctionSequence 

pub struct FunctionSequence { /* private fields */ }

A sequence of functions represented as closures.

Implementations

impl FunctionSequence

pub fn new(functions: Vec<Box<dyn Fn(&[f64]) -> f64 + Send + Sync>>) -> Self

Construct from a vector of boxed functions.

pub fn len(&self) -> usize

Length of the sequence.

pub fn is_empty(&self) -> bool

Is the sequence empty?

pub fn eval(&self, n: usize, x: &[f64]) -> f64

Evaluate f_n at x.

pub fn epi_liminf(&self, x: &[f64], radius: f64, grid_steps: usize) -> f64

Compute epi-liminf at x using a discrete grid of perturbation vectors. epi-liminf_n f_n(x) = liminf_{y→x} liminf_n f_n(y).

pub fn epi_limsup(&self, x: &[f64], radius: f64, grid_steps: usize) -> f64

Compute epi-limsup at x.

pub fn gamma_liminf(&self, x: &[f64], radii: &[f64]) -> f64

Approximate Γ-liminf of the sequence at x. Γ-liminf_n f_n(x) = sup_{U∋x} liminf_n inf_{y∈U} f_n(y).
