Description

While I was studying Markov Chain I had to find the maximum absolute value of the Matrix to divide the matrix in numbers from 0 to 1 to be able to make further analysis. Like this:

q = Matrix[ ... ]
max = q.to_a.flatten.map { |e| e.abs }.max
q = q / max

So this is the first of two features that I would like to contribute.

  1. Matrix.abs
  2. Matrix.max
