gaussian_curve_fit
A no_std
and no alloc
library for gaussian curve coefficents calculation.
example
let mut gaussian_coes = GaussianCoefficents2D::default();
let xdata = [
-8.0f32, -6.0f32, -4.0f32, -2.0f32, 0.0f32, 2.0f32, 4.0f32, 6.0f32,
];
let ydata = [
6.7f32, 10.6f32, 13.5f32, 15.7f32, 16.6f32, 15.4f32, 14.2f32, 10.3f32,
];
let (x_arr, y_arr) = GaussianCoefficents2D::get_matrix_data_from_8_points(&xdata, &ydata);
let _ = gaussian_coes.get_coefficents_from_8_matrix_data(&x_arr, &y_arr, 1e-4);
assert!((gaussian_coes.value(-8.0f32).unwrap_or_default() - 6.7f32).abs() < 1.0f32);
assert!((gaussian_coes.value(-4.0f32).unwrap_or_default() - 13.5f32).abs() < 1.0f32);
