Ruby | Matrix square?() function

Last Updated : 07 Jan, 2020

The square?() is an inbuilt method in Ruby returns a boolean value. It returns true if it is a square matrix, else it returns false.

Syntax: mat1.square?()

Parameters: The function needs the matrix to be checked for square matrix or not.

Return Value: It returns true if it is a square matrix, else it returns false.

Example 1:

# Ruby program for square?() method in Matrix 
  
# Include matrix  
require "matrix"
  
# Initialize a matrix  
mat1 = Matrix[[3, 12], [2, 8]]   
  
# Prints if square? or not  
puts  mat1.square?() 

Output:

true

Example 2:

# Ruby program for square?() method in Matrix 
  
# Include matrix  
require "matrix"
  
# Initialize a matrix  
mat1 = Matrix[[1, 0], [0, 1], [1, 2]]   
  
# Prints if square? or not  
puts  mat1.square?() 

Output:

false
