Ruby | Matrix determinant() function

Last Updated : 07 Jan, 2020

The determinant () is an inbuilt method in Ruby returns the determinant of the given matrix.

Syntax: mat1.det() Parameters: The function does not accepts any parameter. Return Value: It returns the determinant of the given matrix.

Example 1:

Ruby

# Ruby program for determinant() method in Matrix

# Include matrix 
require "matrix"

# Initialize a matrix 
mat1 =  Matrix[[1, Complex(2, 1)], [Complex(8, -9), 18]]       

# prints the determinant 
puts  mat1.determinant()

Output:

-7+10i

Example 2:

Ruby

# Ruby program for determinant() method in Matrix

# Include matrix 
require "matrix"

# Initialize a matrix 
mat1 =  Matrix[[1, 1, 5], [4, 1, 5], [11, 2, 12]]       

# prints the determinant 
puts  mat1.determinant()

Output:

-6
