红宝石 |矩阵+方法

+是 Ruby 中的一个内置方法，它返回一个矩阵，其中添加了两个矩阵 mat1 和 mat2。

Syntax: mat1 + mat2

Parameters: The function need two matrix mat1 and mat2 which are to be added.

Return Value: It returns the resultant matrix after addition.

示例 1 ：

# Ruby program for + method in Matrix
# Include matrix 
require "matrix"
   
# Initialize a matrix 
mat1 = Matrix[[1, 2, 6], [3, 4, 8], [12, 1, 3]] 
mat2 = Matrix[[1, 2, 6], [3, 4, 8], [12, 1, 3]] 
   
# Prints the value of mat1+mat2
puts  mat1 + mat2

输出：

Matrix[[2, 4, 12], [6, 8, 16], [24, 2, 6]]

示例 2 ：

# Ruby program for + method in Matrix
# Include matrix 
require "matrix"
   
# Initialize a matrix 
mat1 = Matrix[[1, 21, 6], [31,124, 18]] 
mat2 = Matrix[[1, 12, 16], [31, 43, 28]] 
   
# Prints the value of mat1+mat2
puts  mat1 + mat2

输出：

Matrix[[2, 33, 22], [62, 167, 46]]
