Ruby | Matrix orthogonal? function

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

Syntax: mat1.orthogonal?()

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

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

Example 1:

#Ruby program for orthogonal ? () method in Matrix

#Include matrix
require "matrix"

#Initialize a matrix
    mat1
    = Matrix[[ 1, 21 ], [ 31, 18 ]]

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

Output:

false

Example 2:

#Ruby program for orthogonal ? () method in Matrix

#Include matrix
require "matrix"

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

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

Output:

true
