红宝石 |向量 to_matrix()函数

to_matrix()是 Ruby 中的一个内置方法，它返回带有向量元素的单列矩阵。

Syntax: vec1.to_matrix()

Parameters: The function accepts no parameter

Return Value: It returns the matrix of single column with elements of vector

示例 1 ：

# Ruby program for to_matrix() method in Vector
      
# Include matrix 
require "matrix"  
     
# Initialize the vector
vec1 = Vector[1, 2, 3]
     
# Prints the matrix with single column
puts vec1.to_matrix()

输出：

Matrix[[1], [2], [3]]

示例 2 ：

# Ruby program for to_matrix() method in Vector
      
# Include matrix 
require "matrix"  
     
# Initialize the vector
vec1 = Vector[1, 1]
     
# Prints the matrix with single column
puts vec1.to_matrix()

输出：

Matrix[[1], [1]]
