While doing math in Ruby is little more challenging than Python or R, it is still my favorite language! Here is how we create simple matrix with Ruby with matrix class and do a simple multiplication.
require 'matrix' matrix_a = Matrix[[1, 2], [3, 4]] matrix_b = Matrix[[-3, -8, 3], [-2, 1, 4]] result = matrix_a * matrix_b # => Matrix[[-7, -6, 11], [-17, -20, 25]]
