As Richard made me notice by email, tests 5 and 6 (using randi and non-integer) were not enable. As I have rescored all solutions, some previous solutions which passed the test, do not pass it anymore.
Can you please set a tolerance for the submitted answers? Using exp(log(x)+log(y)) fails nearly all possibilities for test case 5, with the biggest error being roughly 2.5e-11.
Nice one. It would be more challenging to add a test case where both function arguments are decimal numbers. :)
You can try adding, and something wonderful happens.
Most foul one
exp(log(x)+log(y)) works with a trivial amount of roundoff error. Matlab is a numeric language. Using Isequal() is dumb.
i cant understand why test 1 fails :/
It fails because you use the minus sign and there is the following test :
good use of 'linspace'
What if _both_ x _and_ y were either negative or non-integers though?
Test 1 is always showing Fail. This is disgusting. May be some error on the creator part. Kindly check...
The error for Test 1 says "Output argument 'output' (and maybe others) not assigned". Close examination of your code reveals that when x is 1 and y is 2, you go down the first switch of the outer "if" statement, and sure enough, output never gets assigned and the function fails.
Only works for scalars of course.
