  • Last Updated : 07 Jan, 2020

The is an inbuilt method in Ruby returns a matrix which has the subtraction of two matrix mat1 and mat2.

Syntax: mat1 mat2

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

Return Value: It returns the resultant matrix after subtraction.

Example 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

Output:

Matrix[[0, 0, 0], [0, 0, 0], [0, 0, 0]]

Example 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

Output:

Matrix[[0, 9, -10], [0, 81, -10]]
