"What do you recommend if I have empty array elements?"
Use DATETIME instead of deprecated DATENUM:
B = ["01/01/2008";""]
D = datetime(B, "InputFormat","dd/MM/yyyy")

Unless you're using an older release where it is not available I strongly recommend you use datetime instead of serial date numbers. Note I've changed your B slightly to make it clear that datetime is importing it correctly, not confusing the day and month information.
B = "02/03/2008";
dt = datetime(B, "InputFormat", "dd/MM/yyyy")
With a datetime array a lot of operations are easier and easier to interpret than with a list of date numbers. As an example, what's the day after dt?
nextDay = dt + days(1)
