I learned about fliplr() in another problem and it is helpful here!

Thanks for the hint

I like you're use of a nested loop here.

The last test suite result should be 14.

yes ı agree

Trickey ONE indeed !!

But you can't rely on x always being a magic square - that's just an accident of the inadequate test suite, isn't it? So although this *looks* like a good solution, it isn't really. I think it's bad practice to take advantage of an inadequate test suite.

it doesn't find the sum of the elements of the second but first diagonal
