previous output as the next step input

a simple question from a new learner :

y(n)=y(n-1)+y(n-2)+x(n)

x(n) and y(n) are two different functions. n is an array starting from 0 to 100. Is there any simple way to realize it?  Thanks a lot!

Look up autoindexing and shift registers in the help files.

The context help and the detailed help files are the first place to look for information about how LabVIEW does things.

The tutorials would also be very good for a new learner.
