Ruby | Matrix imaginary() function Last Updated : 07 Jan, 2020 Summarize Comments Improve Suggest changes Share Like Article Like Report 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]] Comment More infoAdvertise with us Next Article Ruby | Numeric imaginary() function G gopaldave Follow Improve Article Tags : Ruby Ruby-Methods Ruby Matrix-class Similar Reads Ruby | Matrix imag() function The imag() is an inbuilt method in Ruby returns a matrix with only imaginary part in it.
