§Examples

use russell_lab::{vec_copy, Vector, StrError};

fn main() -> Result<(), StrError> {
    let u = Vector::from(&[1.0, 2.0, 3.0]);
    let mut v = Vector::from(&[-1.0, -2.0, -3.0]);
    vec_copy(&mut v, &u)?;
    let correct = "┌   ┐\n\
                   │ 1 │\n\
                   │ 2 │\n\
