I.m facing a little issue to combine arrays in a certain manner. Let's say we have a=array([[1,1,1],[2,2,2],[3,3,3]]) b=array([[10,10,10],[20,20,20],[30,30,30]]) I wish to get

c=array([[[1,1,1],[10,10,10]],[[2,2,2],[20,20,20]],[[3,3,3],[30,30,30]]])

The real issue is that my arrays a and b are much longer than 3 coordinates!

The best I achieved using concatenate is:  concatenate((a,b),axis=2) which results in  array([[ 1, 1, 1, 10, 10, 10], [ 2, 2, 2, 20, 20, 20], [ 3, 3, 3, 30, 30, 30]]) it is pretty good but not have enough depth.

Also, I've tried something from another question to get the desired depth:  d=concatenate((a[...,None],b[...,None]),axis=2) but result in: `array([[[ 1, 10], [ 1, 10], [ 1, 10]],

   [[ 2, 20],
    [ 2, 20],
    [ 2, 20]],

   [[ 3, 30],
    [ 3, 30],
    [ 3, 30]]])

` Which still does not works...
