First, fix the syntax errors. You are missing commas in some of your method definitions and adding spaces after the '@' character in your instance variables. There may be other issues, but the Ruby runtime should point them out to you when you try to load and execute your code.

To answer your question about adding a setter/getter for the MATRIX class, you could define #[] and #[]= for that purpose to delegate to your @array ivar.

e.g.

def [](index)
  @array[index]
end

def []=(index, value)
  @array[index] = value
end

Hope this helps. Welcome to Ruby!
