Ruby | Matrix determinant() function

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 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 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
