Ruby | Matrix ** method

Last Updated : 07 Jan, 2020

The ** is an inbuilt method in Ruby returns the matrix after the matrix is multiplied with self N times. It returns the matrix exponentiation value.

Syntax: Matrix_name ** (number)

Parameters: The function takes a mandatory parameter number which signifies the number of times it will be multiplied with self.

Return Value: It returns the resultant matrix after multiplication.

Example 1:

# Ruby program for ** method in Matrix 
# Include matrix  
require "matrix"
  
# Initialize a matrix  
mat = Matrix[[12,41], [61,81]]  
  
# Prints the matrix value after  
# multiplying it 3 times with self  
puts  mat ** 3

Output:

Matrix[[264333, 417298], [620858, 966615]]

Example 2:

# Ruby program for ** method in Matrix 
# Include matrix  
require "matrix"
   
# Initialize a matrix  
mat = Matrix[[1, 2, 6], [3, 4, 8], [12, 1, 3]]  
   
# Prints the matrix value after  
# multiplying it 2 times with self  
puts  mat ** 2

Output:

Matrix[[79, 16, 40], [111, 30, 74], [51, 31, 89]]
