Rather than using the completely ambiguous date format shown in your question, you should consider using an unambiguous ISO 860 date format:

which has the the significant benefit that lexicographical order is also chronological order.

You can try this:

file_name = 'doc3.mat';
file_name = [file_name(1:end-4) datestr(now(),'mmddyyyyhhMM') file_name(end-3:end)];
% then save mat file with name file_name

It wasn't clear from your example whether 04/06 means April 6 or 4 June, this command assumes the month is first. To do day first, swap the 'mm' and 'dd'.

I did it and and last i wrote:

Save file_name.mat mat

But just file file_name.mat saved in directory.

I corrected file to file_name(1:end-4), but still it does not file name as i preffered

save(file_name, 'Meas');

Posters with little activity so far, like you, can (I believe) post up to 10 questions per day.
