Using self reference in WHERE statement? [message #82048] Sat, 10 November 2012 19:04

Hi all,

I have a vector of data with a timestamp. From that vector, I would like to select each element whose timestamp is more than 5 minutes past the previous element's timestamp.

This is easy to do in a FOR NEXT loop, but not very IDL'ish. Is there a way to for instance use a WHERE statement which self references a preceding or a succeeding element as a criterion?

Can anyone think of an IDL'ish way to do this?

Cheers
