Jess Stuart submitted a Comment to Problem 156. Parasitic numbers

Can the problem creator disqualify "solutions" that cheat? There should be a point penalty (-200) associated with cheating too.

exp(log(x)+log(y)) works with a trivial amount of roundoff error. Matlab is a numeric language. Using Isequal() is dumb.

Nice little bug in there.

Should add tolerance of 10*eps to make this function practical. Otherwise you can have a triangle with a 89.9999999 deg angle and it will say it is not a right triangle. Matlab is a numerical language.

Your weight vector should be a unit vector. W=w/norm(w) to get a true weighted average. Dividing by the max is dumb.

Jess Stuart submitted a Comment to Problem 2033. poll: would you like the regexp (?@cmd) functionality to be banned in Cody?

Is there a way to parse the code inside the regex and assign an appropriate size to it? That would seem like the most fair thing to do.

Jess Stuart submitted a Comment to Problem 42775. Raise a polynomial to a power

Thought of another way to do this... q=poly(kron(roots(p),ones(N,1))); One-liner with size 21, but fails because of trivial roundoff error :(
