OK, here is a simplified example of what I'm trying to do:
I want to split a matrix into two, so that the result is composed of the
odd rows and even rows of the matrix respectively

e.g.

     oddevenrows  i. 6
  0  1  2
  6  7  8
12 13 14

  3  4  5
  9 10 11
15 16 17

I'm thinking, should I use select or cut or something else.  Long day.
