How to interleave arrays in julia

Question

Is it possible to interleave two arrays in julia?

For example if a=[1:10] and b=[11:20] I want to be able to return

20-element Array{Int64,1}:
  1
  11
  2
  12
  3
  13
  4
  14
  .
  .
  .

Somewhat similar to what ruby can do Merge and interleave two arrays in Ruby

Answer 1

Figured it out!

reshape([a b]',20,1)

and for something more general:

reshape([a b].',size(a,1)+size(b,1),1)

we can use a hack to get vectors instead of 1D arrays:

reshape([a b].',size(a,1)+size(b,1),1)[:]
