Ruby | Matrix imaginary() function

Last Updated : 07 Jan, 2020

The imaginary() is an inbuilt method in Ruby returns a matrix with only imaginary part in it. The other index are assigned to zero.

Syntax: mat1.imaginary() Parameters: The function does not takes any parameter. Return Value: It returns a matrix with only imaginary part.

Example 1:

CPP

#Ruby program for imaginary() method in Matrix

#Include matrix
require "matrix"

#Initialize a matrix
    mat1
    = Matrix[[ Complex(1, 2), 21 ], [ 31, Complex(9, 12) ]]

#prints the imaginary part
      puts mat1.imaginary()

Output:

Matrix[[2, 0], [0, 12]]

Example 2:

CPP

#Ruby program for imaginary() method in Matrix

#Include matrix
require "matrix"

#Initialize a matrix
    mat1
    = Matrix[[ Complex(19, 3), Complex(12, 3) ], [ Complex(7, 8), Complex(91, 2) ]]

#prints the imaginary part
      puts mat1.imaginary()

Output:

Matrix[[3, 3], [8, 2]]
