I just want to make a simple question: is there a way to make arrays,
vectors and matrices with SESSION VARIABLES on Ruby and Rails? I’m
making a Rails app and I need to save all the data in session
variables before saving it to the DB. the catch here is the following
logic:
element1 has many element2s values stored
element2 has many element3s values stored
Can the arrays be as many dimensions as I want? Because I took a look
on how to make the vector and matrices and it looks complicated. No
offense. Is there and example where I can do such a thing with arrays?

Personally I would save the matrix and vector classes for actually
doing matrix math.
I think your specification of the problem so far is not concrete
enough for me to be able to volunteer a solution, but you can
certainly have something like
x = [[[1,2,3], [4,5,6]],[[7,8,9],[10,11,12]]]
x[0][1][2] #=> 6
At this point this isn’t really a rails question any more - you may
find more opinions on the ruby-talk list.
