d = 726329;
datetime(d, 'ConvertFrom', 'datenum', 'Format', 'dd-MM-yy') %recommended, although I'd recomend using yyyy instead of yy
%or
datestr(d, 'dd-MM-yy') %not recommended
I would recommend that you use the newer datetime instead of the old datestr. I would also recommend that you use 4 digits for the year. Hasn't Y2K and all the subsequent scares taught us enough that using 2 digits for the year is foolish.

@Guillaume: Y2K does not work here. I've tried 'dd-MM-kk', but get an error message only.

@Jan, Y2k is not a format. It's the short name for the scare we had before 2000 because critical computers stored the year using only two digits. More recently, we had the gps rollover scare again because programmers skimped on the number storage.
There's really no reason not to store the year using 4 digits and remove any kind of ambiguity over which century/millenium is meant. 2088 is only 69 years away, some of the young ones here may still be alive by then, so remove the ambiguity with 1988.
