You need to assign your answer to the output variable tf.

Look at your result carefully when n = 4.

Ned Gulley submitted a Comment to Problem 1686. Generate a melodic contour string matrix

I admit they look wrong, but the actual text in the MATLAB code runs properly. I just re-scored some answers and they worked fine. It must be some kind of HTML display problem. I'll check into it.

Ned Gulley submitted a Comment to Problem 44265. Practical 1, Question 2b (incomplete)

Hi Peter: If your problem is still incomplete, just leave it in draft mode. Don't publish it until it's complete.

Good point. Fixed this.

Ned Gulley submitted a Comment to Problem 581. Function composition

I guess the name needed changing, but be aware that if we ever re-score old entries, everyone who passed before the name change will now fail, since they will now be calling the wrong function.

Good suggestion. I made the change.

Ned Gulley submitted a Comment to Problem 43886. Degrees to Radian

Hi Jared. If you're going to make problems that have approximate floating point answers (often the case with conversions), you need to allow for some variation in your test suite. ISEQUAL is not a good test in these cases. Instead, maybe use ABS(answer-correct) < tolerance.

Ned Gulley submitted a Comment to Problem 43830. MPS to MPH

Hi Jared. Please specify what MPS means. I assumed it meant meters/second. I had to inspect your test suite to figure out you meant miles/second. Also, your problem title says MPH to MPS, but the actual problem is to convert MPS to MPH.

Hi Peng, and thanks for the note. I see your solutions now do quite well with all test cases! :-)

Good catch James! Thanks. That was a data entry problem. Should be fixed now.

I would love to find a way to get people "liking" problems more often. Liking makes the author feel good about a job well done, but more importantly it points people to good problems. Sometimes we try to motivate people to like problems. This happened with the October triathlon contest (when the problem you reference was created). But it can have an unintended outcome of encouraging people to like problems that aren't that great. The results are very uneven. Bottom line: if you like a problem, please "like" it!
