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.

Given the limited test suite due to the nature of the question, it can be easily solved by hard-coding.
