I am trying to iterate a multidimension array created with the following line

To iterate i'm using the following code

visiblematrix= Array.new (10) {Array.new(10){0}}

But this doesn't allow me to know the current x,y position while iterating. how can i find it out without resorting to temporary variables

visiblematrix.each do |x|
            x.each do |y|
                  puts y
            end 
end
