Struct optimization_engine::constraints::Ball2

pub struct Ball2<'a> { /* private fields */ }

A Euclidean ball, that is, a set given by $B_2^r = \{x \in \mathbb{R}^n {}:{} \Vert{}x{}\Vert \leq r\}$ or a Euclidean ball centered at a point $x_c$, that is, $B_2^{x_c, r} = \{x \in \mathbb{R}^n {}:{} \Vert{}x-x_c{}\Vert \leq r\}$

Implementations

impl<'a> Ball2<'a>

pub fn new(center: Option<&'a [f64]>, radius: f64) -> Self

Construct a new Euclidean ball with given center and radius If no center is given, then it is assumed to be in the origin
