Ruby vec1.cross_product(vectors)函数

cross_product() 是Ruby中一个内置的方法，用于返回给定向量的交叉积 。

语法 ：vec1.cross_product(vectors)

参数 ：该函数接受向量作为参数

返回值 : 它返回给定向量的交叉积

例子 1 :

#Ruby program for cross_product() method in Vector
 
#Include matrix
require "matrix"
 
#Initialize the vector
    vec1
    = Vector[1, 2, 3] vec2 = Vector[2, 1, 4]
 
#Prints the cross product of vectors
                             puts vec1.cross_product(vec2)

输出:

Vector[5, 2, -3]

例2 :

#Ruby program for cross_product() method in Vector
 
#Include matrix
require "matrix"
 
#Initialize the vector
    vec1
    = Vector[1, 2, 3, 4] vec2 = Vector[2, 1, 4, 1] vec3 = Vector[2, 4, 5, 7]
 
#Prints the cross product of vectors
                                                          puts vec1.cross_product(vec2, vec3)

输出:

Vector[7, -5, -3, 3]
