Function russell_lab::check::array_approx_eq

pub fn array_approx_eq<T>(u: &[T], v: &[T], tol: f64)
where
    T: Num + NumCast + Copy,

Panics if two arrays (vectors) are not approximately equal to each other

Panics

1. Will panic if the dimensions are different
2. Will panic if NAN, INFINITY, or NEG_INFINITY is found
3. Will panic if the absolute difference of components is greater than the tolerance

Examples

Accepts small error

use russell_lab::array_approx_eq;

fn main() {
    let u = vec![3.0000001, 2.0];
    let v = vec![3.0,       2.0];
    array_approx_eq(&u, &v, 1e-6);
}

Panics on different value

use russell_lab::array_approx_eq;

fn main() {
    let u = vec![3.0000001, 2.0];
    let v = vec![4.0,       2.0];
    array_approx_eq(&u, &v, 1e-6);
}
