title: Julia: Transforming an Array of Arrays in a 2-dimensional Array
body: <p>I have an Array <code>d</code> that contains an Array of floats:</p>
  
  <pre><code>julia&gt; d
  99-element Array{Array{Float64,1},1}:
  ...
  </code></pre>
  
  <p>I'm trying to convert it into a 2-dimensional Array, and I sucessfully achieved my goal with:</p>
  
  <pre><code>data = Array(Float64,length(d),length(d[1]))
  for i in 1:length(d)
      for j in 1:length(d[1])
          data[i,j] = d[i][j]
      end
  end
  </code></pre>
  
  <p>Is there a simpler way of doing this?</p>
