You're making a 2D array, for which there is a dot add method. Chris, the OP, is making an array of arrays. I wonder if that is really what he wants?
*julia> **a = fill(1, 5,2)*
*5x2 Array{Int64,2}:*
* 1 1*
* 1 1*
* 1 1*
* 1 1*
* 1 1*
*julia> **a + 1*
*5x2 Array{Int64,2}:*
* 2 2*
* 2 2*
* 2 2*
* 2 2*
* 2 2*
