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.
make sure to round the inverse of B, it's the reason 1&2 test cases are incorrect.
i tried all the things but I am not able to solve this question can anybody help me with this question
@Sayali Recall that if A is the inverse B, then AB = BA = I, where I is an identity matrix of appropriate dimensions. Also, brush up on your basic MATLAB, e.g. syntax and built-in functions. Good luck!
