This solution only tests for divisibility by 9, not whether the number is a Kaprekar number.

the cyclist submitted a Comment to Problem 151. Magic!
The MATLAB command magic(2), although it does produce output, is not a magic square, according to the definition. (There is no 2x2 magic square.)

the cyclist submitted a Comment to Problem 151. Magic!
I was not notified about some of the older comments, so was unaware of some of the weaknesses of the test suite, and the "gamed" solutions. I have substantially improved the test suite.

I somehow Alfonso's older comment until I saw Tom's newer one.
Alfonso: I've added a non-sorted test sample, and had the problem rescored.
Tom: 1 is neither prime nor composite. I've added instructions on how to handle that.

It looks like your solution uses the symbolic math toolbox. I am assuming that that is not available to Cody solutions.

I added additional cases to the test suite, so this attempted solution is incorrect now.
