Hello,
I'm trying to make an array of size n*n*2.  It should be of the form:
[[[0,0],[1,0],[2,0],[3,0],[4,0], ... ,[n,0]],
 [[0,1],[1,1],[2,1],[3,1],[4,1], ... ,[n,1]],
 [[0,2],[1,2],[2,2],[3,2],[4,2], ... ,[n,2]],
 [[0,3],[1,3],[2,3],[3,3],[4,3], ... ,[n,3]],
 [[0,4],[1,4],[2,4],[3,4],[4,4], ... ,[n,4]],
   ...   ...   ...   ...   ...   ...   ...
 [[0,n],[1,n],[2,n],[3,n],[4,n], ... ,[n,n]]]
Each vec2 represents the x,y position of the vec in the array itself.  I'm
completely stuck on implementing this setup in numpy.  Any pointers?

Thanks,
Ian
