Two sided moving average in matlab

[Ysdream]

Hi
I have weather data every 5 minutes for two weeks and i want to do two-sided moving average filtering in matlab.
My question is what is the command and how to decide values in the command
Like window size etc...

Just use the right commands and everything should be fine

I am asking about the command actually as i cannot find it. Also about deciding window size!
