MATLAB: How to align date formats

Question

Hi, I have some dates I need converted to the same format. I've boiled it down to the following possible formats but now I'm stuck:

01/01/2016

1/01/2016

01/1/2016

1/1/2016

I need them all to be: 01/01/2016

I've tried a few things but nothing works without messing up something else at this point.

Answer 1

dates = {'01/01/2016', '1/01/2016', '01/1/2016', '1/1/2016'};
datestr(datenum(dates), 'dd/mm/yyyy')
