gather() in tall array inverse is incorrect

Hi,
I am testing simple code with tall array inverse and gather(). The following results are different, anyone knows how to fix gather? As I am using tall array for AA and bb.
AA = ones(13,9);
bb = ones(13,1);
AA_t = tall(ones(13,9));
bb_t = tall(ones(13,1));
gather(AA_t\bb_t);
AA \ bb;

"why gather()cannot evaluate the same results as non-tall array case?"
For efficient handling of the different data types they use different algorithms. No surprises there.
"Is there a solution to make consistent results: A/b and gather(A_t/b_t)? They all have the rank deficient issue"
There are infinitely many solutions. Why should we expect any one solution to be preferred?

Hi Chen,
please modify this line and see whether the issue persists or not!
gather(AA_t)\gather(bb_t);
