Trait cobyla::CstrFn

pub trait CstrFn: Fn(&[f64]) -> f64 { }

A trait for a constraint function which should be positive eventually

A constraint function takes the form of a closure f(x: &[f64]) -> f64 The algorithm makes the constraint positive eventually.

For instance if you want an upper bound MAX for x, you have to define the constraint as |x| MAX - x. Conversly for a lower bound you would define |x| x - MIN

• x - n-dimensional array
