So, I have the following array:
v =
[1 2 3;
-1 2 -3;
0 0 0;
1 -2 3;
1 2 3;
1 2 3;
0 0 0;
0 0 0;
1 1 1]
I would like to split it into several arrays that I can call upon later as follows:
v_1 = [1 2 3; -1 2 -3],
v_2 = [1 -2 3; 1 2 3; 1 2 3],
v_3 = [1 1 1];
How would I go about doing this. I would like to use the zeros as an indication of where to create another variable with the array indicated.
Thank you.

I know you asked that, but do NOT go down that perilous pathway..."There be dragons!"

"...but I would again like to call them each from a vector. Thoughts?"
Do NOT do that. Magically accessing variable names is one way the beginners force themselves into writing slow, complex, buggy code. Here is why:

v is not a vector but an array.
Star's code works on a vector; would be painful to extend to an array I think, as is. BUT, you can create a vector to use to find the split locations by his technique and then select the array instead of vector.
Define the auxiliary vector as
aux=all(v==0,2);
