Hello. I would like to produce a date (for instance: 7th of January 2014) string looking like '20140107' for representing YYYYMMDD, but a one digit M and D currently results in the unwanted string '201417', which is only YYYYMD.

[Y, M, D, H, MN, S] = datevec(now);
dateString =[num2str(Y),num2str(M),num2str(D)];

Any idea how to get YYYYMMDD always as a 8 digit string, something which is simpler than this?

You might like to consider my File Exchange submission, which converts to ISO 8601 date formats:
