precision issues, a single test case, meaningless "not using built-in functions" limitation, and somewhat taunting "have a pride" exhortation... please do the same and put some more thought into your problem
Updated TSuite now
Humm. the test suite is actually requesting Gaussian elimination, not LU decomposition. You may check it by using [L,U] = lu(x). They are very similar processes, but not exactly the same.
Not a built in function, but still a very cheesy answer! :-)
I see you! hahahaha
