Team,

What is the easiest way to initialize a square matrix?
For example, to initialize a 3x3 array elements to 0, I am doing what you
see below. But I am not sure how to proceed if, for instance, I want a NxN
array where N > 10 or a huge value?
I played a bit on IRB but could not find the way to do it easily.

irb(main):008:0> ary = Array.new(9,[0,0,0])
=> [[0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0,
0], [0, 0, 0], [0, 0, 0]]

Thank you
