Subject: adding array of numbers

Given a file that looks like so:
  7                             ==> training Set length
  11                            ==> file length
  1  0  0  0  0  1  0       0
  0  1  1  1  0  0  1       0
  1  0  1  0  1  0  1       1
  1  0  1  1  1  1  1       1
  0  0  1  0  1  1  1       1
  1  1  0  1  0  1  1       0
  0  0  0  1  0  1  0       1
  1  1  0  0  1  0  0       1
  1  1  0  0  0  0  0       0
  0  1  0  1  0  1  1       0
  1  1  1  1  1  0  0       0 ==>end of file
       #training set       #Answer
For now, I need to do this : get the dotProduct of the vector training
set and weight vector, and if that number is > 0 , output 1 ,else output
0. later in the problem I compare that to the answer, but I'm not there
yet. Here is what I have(with tests) to try to get 1 training set to add
up all numbers(without the dotProduct of weights) using IO.readlines,
splitting each line using split,  for  loops to get an array of integers
to be added together to get output for Perceptron_Bond object named
einstein.  coding is as follows
class Perceptron_Bond

attr_reader :weights, :output
attr_writer :weights, :output
def initialize(input, weights)
  @weights = weights
  @input =input
end


  def output
     y = @input.inject(0) {|sum, element | sum+element}
     @output=y
     end
end
   str = ARGV[0]
   inputs = Array.new
   inputs1 = Array.new
   inputsNum = Array.new
   setArr = Array.new
   answers = Array.new
   arr = IO.readlines(str)


   arr.shift
   arr.shift

   arr.each { |y| inputs1.push(y.split)}
   inputs1.each do|x|
     answers.push(x.last)
     x.pop
end
  for i in 0...inputs1.length
  setArr[i]= Array.new
  for j in 0...inputs1[i].length
  inputsNum[j] = Array.new
  inputsNum[j].push(Integer(inputs1[i][j]))
  if j==(inputs1[i].length-1) then
    inputs[i] = inputsNum
    end
  end
puts inputs[i].to_s

end
puts inputs.to_s
puts inputs[2][1].class  ==> Array #i want fixnum

   initWeights = Array.new(inputs.length) { |index| index =0 }
   einstein = Perceptron_Bond.new(inputs[0] , initWeights)
   puts einstein.output  #should produce fixnum 2
i get an error as well in output telling me I cannot coerce an Array to
a fixnum
Im guessing its stemming from the nested for loops I have, but I am just
stumped
I need help in a bad way, please.
