rust 矢量叉乘

## Vector Cross Product in Rust.

In mathematics, the cross product is a binary operation

on two vectors in three-dimensional space that results in a

vector perpendicular to both of the original vectors. The

cross product is often used to calculate the area of a

parallelogram, the volume of a parallelepiped, and the

normal to a plane.

In Rust, the cross product of two vectors can be

calculated using the `cross` method of the `Vec3` type. The

`cross` method takes two `Vec3` values as input and returns

a new `Vec3` value representing the cross product of the

two input vectors.

use nalgebra as na;

fn main() {。

let a = na::Vector3::new(1.0, 2.0, 3.0);

let b = na::Vector3::new(4.0, 5.0, 6.0);

let c = (&b);

println!("The cross product of a and b is: {:?}",

c);

}。

Output:

The cross product of a and b is: Vector3 { x: -3.0, y:

6.0, z: -3.0 }。

## 向量叉乘。

在数学中,叉乘是在三维空间中两个向量的二元运算,所得结

果是一个垂直于两个原始向量的向量。 叉乘通常用于计算平行四边

形的面积、平行六面体的体积和平面的法线。

在 Rust 中,可以使用 `Vec3` 类型的 `cross` 方法来计算两

个向量的叉乘。 `cross` 方法将两个 `Vec3` 值作为输入,并返回

一个新的 `Vec3` 值,表示两个输入向量的叉乘。

use nalgebra as na;

fn main() {。

let a = na::Vector3::new(1.0, 2.0, 3.0);

let b = na::Vector3::new(4.0, 5.0, 6.0);

let c = (&b);

println!("The cross product of a and b is: {:?}",

c);

}。

输出:

The cross product of a and b is: Vector3 { x: -3.0, y:

6.0, z: -3.0 }。
