# burst duration

I'm looking at a simple temperature time series over many years. I'm trying to investigate the duration of bursts in above a specific threshold temperature in this series but can't think of a way for Matlab to search for these bursts and output the duration of them. So far all I have come up with is a for loop with a lot of if statements inside but this is very taxing on cpu and ram and takes a long time. Can anyone think of a quicker way to output this kind of information?

Long story short, I'm trying to investigate the number of consecutive values in a vector that are greater (or less) than a threshold value.

I do not know what do you mean by consecutive values. You mean 1,2,3,4,5,6,7... consecutive? Or 1,1,1,1,1,1,1.. consecutive?
You can try:-
temp = data - threshold;
position = find(temp>0);
That is if you are going for positions of data greater than a threshold value. If it is case B of consecutive values then you are done. If you are looking for a pattern, manipulate the position data you found.
