To my last question, it does not need to increase by exactly 20, just 20 or more. Could I write: col3select=[0; doff(info(:,3))] >20;

Well, you want greater-or-equal. So replace the == with >=
Also, if you want to clarify an answer to a question, please write a comment on the particular answer instead of starting a new question.
Edit, following new revelations =P
Okay, you used confusing language and did not explain your problem clearly.
There may be clever ways to do this is, but I think you would benefit most from a simple and self-explanatory loop:
overThreshold = false;
col3select = false(size(info,1), 1);
for r = 1:size(info,1)
if info(r,3) >= 520
overThreshold = true;
elseif info(r,3) <= 500
overThreshold = false;
end
col3Select(r) = overThreshold;
end

ok that worked but how could I change the command so that when it increases by 20 is shows not only that point but all the way until it goes back to its baseline. say the baseline is 500, I want to know the locations where it increases from 500 to 520 or higher and records those positions until it is back down at 500. And to do this for everytime this occurs?

Baseline?? It increases by 20??
If you are talking about a program, which is posted in another thread, please post the link.

Ok, I have a matrix info(10000x3) where (:,1)=time, (:,2)=data2, and (:,3)=data3. For (:,3) data3 the average (baseline) value is 500. I want to find the location in(:,3) data3 where the value increases by 20 or more ~ 520+ , and record that value and keep recording until it returns back to the baseline of 500. I would like todo this each time the value exceeds 500 by 20 or more. Thanks

@Jan: Unfortunately, justin deleted the original question that I answered, because he wanted to ask a question about my answer. But I'm in a good mood today.
