You can use Gauss formula for triangular numbers. It will improve performance. It won't improve Cody size. To improve Cody size, you need hack. Popular hack is to wrap the code into regular expression. Somebody invented it to cheat scoring algorithm and it spreaded among cody submissions like a cancer. I'm not proud of this, I was using this hack too, fortunately realised that it makes no sense. Advice: don't care so much about the size, care about quality code. Most of super small solutions use some sort of cheats, you won't learn much from those.

Jonathan, it is unlikely to get rejected due to small error. After complaints, MathWorks/Cody Team took care about it few months ago. Based on submission times, solutions which may be yours were classified incorrect, because one of criterions is to stop simulation after reaching ground level and those solutions don't include this part.

true, not 'true', false, not 'false'

Note that "c(c==-d) = d" means that c and d must be same size or d is scalar. Moreover if d is not a scalar, then all "c==-d" must be true. This code seems to work in rare case, when one value is negative real number, and the rest are positive real numbers, but I have not tested it.
