Ruby | Matrix singular?() function

Last Updated : 06 Aug, 2024

The

singular?()

is an inbuilt method in

returns a boolean value. It returns true if it is a singular matrix, else it returns false. It returns error if anything other than square matrix is used.

Syntax: mat1.singular?() Parameters: The function needs the matrix to be checked for singular matrix or not. Return Value: It returns true if it is a singular matrix, else it returns false.

Example 1

:

Ruby

# Ruby program for singular?() method in Matrix

# Include matrix 
require "matrix"

# Initialize a matrix 
mat1 = Matrix[[3, 12], [2, 8]]  

# Prints if singular? or not 
puts  mat1.singular?()

Output

:

true

Example 2

:

Ruby

# Ruby program for singular?() method in Matrix

# Include matrix 
require "matrix"

# Initialize a matrix 
mat1 = Matrix[[1, 0], [0, 1]]  

# Prints if singular? or not 
puts  mat1.singular?()

Output

:

false
