如何用ndarray在Rust中做点积？

[dependencies]
ndarray = "0.15.4"

use ndarray::{Array, Array2, Dot};

let a: Array2<f64> = Array::from_shape_vec((2, 3), vec![1.0, 2.0, 3.0, 4.0, 5.0, 6.0]).unwrap();
let b: Array2<f64> = Array::from_shape_vec((3, 2), vec![7.0, 8.0, 9.0, 10.0, 11.0, 12.0]).unwrap();

let c: Array2<f64> = a.dot(&b);

use ndarray::{Array, Array2, Dot};

fn main() {
    let a: Array2<f64> = Array::from_shape_vec((2, 3), vec![1.0, 2.0, 3.0, 4.0, 5.0, 6.0]).unwrap();
    let b: Array2<f64> = Array::from_shape_vec((3, 2), vec![7.0, 8.0, 9.0, 10.0, 11.0, 12.0]).unwrap();

    let c: Array2<f64> = a.dot(&b);

    println!("{:?}", c);
}
