The test suite only seems to work if the n primes each have the same number of digits. For example, with n=3, a perfectly good answer would be [5,7,11], but this crashes the test suite. It could be fixed by using combine=strcat(combine,strtrim(b(i,:)));
@William: your suggestion has been incorporated into the test suite.
Thank you both for improving the quality of this problem. Cheers, Doddy.
