The problem description is broken(?) and you have mentioned the code in the test suite (you might want to remove that)
The test suite has had the "solution" code removed. The description was also cleaned up. (If it's not loading, simply reload the page.) I'm not sure how much these fixes help, though...
Sum the Digits of a Number
select the primes of a vector
find radius of cone
Find out magnitude of vector
provide the numerical answer to these number questions...
Magic Concentric Circles
Convert vector datasets to plot with imagesc instead of scatter
is the number happy?
