Subject: How to operate on 2 arrays simultaneously?

There has got to be a more elegant solution than this.  Suppose I have
2 identical length arrays that I want to add together to produce a
third array.  The best solution I've come up with is:

c = (0...a.size).map {|i| a[i] + b[i]}

Any suggestions?
