矩阵乘法

[![ndarray-badge]][ndarray] [![cat-science-badge]][cat-science]

ndarray::arr2创建两个矩阵，并用ndarray::ArrayBase::dot对它们执行矩阵乘法。

extern crate ndarray;

use ndarray::arr2;

fn main() {
    let a = arr2(&[[1, 2, 3],
                   [4, 5, 6]]);

    let b = arr2(&[[6, 3],
                   [5, 2],
                   [4, 1]]);

    println!("{}", a.dot(&b));
}
