# [−]Struct lumol::energy::Gaussian

Gaussian potential.

$$ V(x) = -a \exp(-b x^2) $$

where $a$ is the potential depth and $b$ is the potential width.

# Restrictions

$b$ has to be positive

# Examples

let potential = Gaussian::new(8.0, 0.5); assert_eq!(potential.energy(0.0), -8.0); assert_eq!(potential.force(0.0), 0.0);

## Methods

`impl Gaussian`

`pub fn new(a: f64, b: f64) -> Gaussian`

Create a new `Gaussian`

potential with a depth of `a`

and a width of `b`
