how to switch contents of two variables?

hey,

I want to write a program that returns the day diffrence between two specific dats. Now,, I want the second date to be the latter chronologicly. If the user type them otherwise I want to switch them. I'm very new at matlab, I tried this but I think It's not good...

    if (date1(1)>date2(1)) && (date1(2)>date2(2)) % I assum it's the same year, date 1 and 2 is a 1X3 vectors.
          date1=date2;
          date2=date1;
       end

what's the right way to do this? thank you very much!

Sai Vaddi:

Use two minmax blocks. Send both signals to both of them. Have one send out the min and the other send out the max. You can combine the two with a mux block afterwards if you want.

Try deal() - it's MATLAB's version of a swap function:

[date2, date1] = deal(date1, date2) % Swap date1 and date2
