How to simply add the date to a file name when saving a file.

Hello, I'm currently working on a program for a final in my Engineering Programming class. The guidelines are as followed:

1.) Generate a function that accept a function and calculates the values of that function from x = a to x = b in step size h

2.) Save the calculated values in a file that is date-stored and "other identities". Examples:

--project 2 dec04mattmunster.dat --proj12042013mmunster.dat

3.) Compare your data to a set of data I will give you in file format

4.) Plot 2 graphs: -1st graph = your data in a subpot and my data in another subplot -2nd graph = your data/my data overlaid

Currently I have the main function in Part 1 completed however I cannot figure out how to created a "date-stored" file name like the examples above in Part 2. Currently I have this:

>>function FinalProject = FinalProject(f,a,b,h)

>>FinalProject = f(a:h:b);

>>dlmwrite(mmunster,FinalProject,',')

>>end

dlmwrite prints out the date perfectly well but I need more than that in the file name like the examples above. Help?

(I don't need assistance with the other parts....yet)

Thank you

get the datestring above, make the filename as per your need with the datestring.

eg:

FileName=['proj',datestr(now, 'dd-mmm-yyyy'),'mmunster.dat'];

use this FileName in your dlmwrite.

Fantastic, works great! Thank You!

Example:

datestr(now, 'dd-mmm-yyyy')

That just prints the date and time, I need that in addition to a file name

ex: project dd-mm-yyyy HH:MM:SS
