Your English is much better than my German, so no problem. All we have to do
is figure out how to communicate the fine points of Ruby code, but without
any code.

From the appearance of your example, it appears that you want to replace the
contents of two middle columns in a 4x3 array with the contents of a 2x3
array. Yes?

#!/usr/bin/ruby -w

array1 = [
   [ 0,0,0,0 ],
   [ 0,0,0,0 ],
   [ 0,0,0,0 ]
]

array2 = [
   [ 1,0 ],
   [ 0,1 ],
   [ 1,1 ]
]

array1.each_index do |i|
   array1[i][1 .. 2] = array2[i]
end

p array1

output:

[[0, 1, 0, 0], [0, 0, 1, 0], [0, 1, 1, 0]]

If this isn't what you had in mind, we'll have to try again.
