Need to improve the test suites.
Test of [1 1;1 1] for x and y would break current best solution
Test suite not proper
just y=1 can pass
Test suite has been improved
Inputs should be changed to be A and B instead of x and y
i think there id some error in test case 1,2
Bit tricky
If you are having issues with this and your solution seems correct, it is likely a computer precision issue.

A bit tricky, just needed to convert float to integer.

check for isdiag(A*B) and an exception for singular matrices

only test case is 1, so no real solution is needed. also the problem seems reversed.

the matrix are given in the problem statement is A,B but function take x
and y and return answer in y that is bit confusing ,any how just use logic A*B^1=I .

really too disgusting prb use isequal(fix(B),round(inv(A)))
or y=true
