incorporated the OP’s clarification that m and n are also part of the things to find; fixed typo pointed out by Brendan McKay in a comment

| Oct 26, 2014 at 0:47 | comment | added | Brendan McKay | I guess $x$ has $n$ entries, not $m$ entries as you have it. | |

| Oct 23, 2014 at 13:26 | comment | added | Per Alexandersson | Have you done any computer searches for small m and n? | |
| Oct 23, 2014 at 13:20 | comment | added | Daishisan | Yes, I did mean whether there exists such an $n$ and $m$. I only said that to stress that $A$ need not be square. I guess it's still worded a bit unclearly. | |
| Oct 23, 2014 at 13:15 | comment | added | J Fabian Meier | Is the question whether there exist any n,m, such that there is such a matrix? (in contrast to the way Per Alexandersson answered?) | |

Reworded question for less ambiguity.

My question was incorrectly worded before regarding the entries of $x - y$.
