Crate fitting

This library provides fitting::Gaussian, which represents gaussian function

Details

Use Gaussian::new to get struct that represents gaussian function.

use fitting::Gaussian;

let gaussian = Gaussian::new(5., 3., 1.);
let x = 5.;
let y = gaussian.value(x);
assert_eq!(&y, gaussian.a());

Use Gaussian::value and Gaussian::values to get value(s) of the function.

use fitting::Gaussian;

let gaussian = Gaussian::new(5., 3., 1.);
let x = 5.;
let y = gaussian.value(x);
assert_eq!(&y, gaussian.a());

Use Gaussian::fit to fitting arrays to the gaussian function.

use fitting::approx::assert_abs_diff_eq;
use fitting::Gaussian;
use fitting::ndarray::{array, Array, Array1};

let gaussian = Gaussian::new(5., 3., 1.);
let x_vec: Array1<f64> = Array::range(1., 10., 1.);
let y_vec: Array1<f64> = gaussian.values(x_vec.clone());
let estimated = Gaussian::fit(x_vec, y_vec).unwrap();
assert_abs_diff_eq!(gaussian, estimated, epsilon = 1e-9);
