Struct ConvexFunction 

pub struct ConvexFunction {
    pub domain: String,
    pub is_proper: bool,
    pub is_lsc: bool,
}

A convex function with domain and lower-semicontinuity properties.

Fields

domain: String

Domain description (e.g., “R^n”, “[0,1]”).

is_proper: bool

Whether the function is proper (not identically +∞, never -∞).

is_lsc: bool

Whether the function is lower-semicontinuous (closed).

Implementations

impl ConvexFunction

pub fn new(domain: impl Into<String>, is_proper: bool, is_lsc: bool) -> Self

Create a new ConvexFunction.

pub fn subdifferential(&self) -> String

Returns a description of the subdifferential of this function.

pub fn conjugate_fn(&self) -> String

Returns a description of the conjugate (Fenchel dual) function.
