Time-series data

Hi everybody,
I have a set of time series data and I have to check if the average values are within the range for a certain amount of time (for example if the parameter X is in the range for 2 minutes).
Is there a matlab function that allows me to do that?
Thank you for your time!

Are you saying you want a series of mean values, similar to an RMS? Or are you looking for a running average?

The 'simplest' way to do a series of mean values is to use a for loop with the mean function.
nmean = 50; % Number of values you would like to average at a time
for i = 1:2*length(data)/nmean
average(i) = mean(data((i-1)*nmean/2:(i-1)*nmean/2+nmean));
end
You may run into an issue with index exceeding matrix dimensions near the end of your data set. If this happens, just reduce the maximum i value by changing the bounds of the loop. If you are not sure how to do that look up the basics of a for loop here.
