How do I find .index of a multidimensional array

Question

Tried web resources and didnt have any luck and my visual quick start guide.

If I have my 2d/multidimensional array:

 array = [[\'x\', \'x\',\' x\',\'x\'

You can use the method Matrix#index:

require 'matrix'

Matrix[*array].index("S")
  #=> [1, 1]
