Changing file names to reflect date

I am generating pdfs based on data that is being read in. I need to use a certain naming convention based on the date. Getting the data I need from the clock funtion is working fine.The problem I am encountering is that some of the functions being used only accept strings has there input and I am unable to change them.

Attempt 1

fv0 = strcat('RM13',num2str(day(1)),'.000', num2str(day(2)))
system('move a.pdf fv0.pdf');

Here I am trying to change the file a.pdf (which contains the processed data) to the naming convention I want but the system function only accepts string inputs I can not update the name.

Attempt2

m6=strcat('SVC_1B_pqpf_',num2str(day(2)),num2str(day(3)),'_13',num2str(day(1)),'.pdf');
print -dpdf m6

Here I am attempting to change the file name as soon as it is written

Note that day is a vector containing the formatted date from clock

You'd need to write fv0 into a string:

commandLine = sprintf('move a.pdf %s.pdf', fv0);
system(commandLine);

But why not use the builtin movefile() to rename?

Thank you, movefile() worked like a charm
