I have a large dataset of 1second time-series data in a timetable. In the dataset I also have a binary flag for when there is a filter in place for backgrounding the measurement. I would like to detect outliers for the signal measurement to remove erroneous points before doing any calculations on the data. Is there a simple way to incorporate the filter flag using isoutlier() so that I can ignore those points without the moving median incorporating the last sample time?

The data set has ~10 million points which makes me want to avoid looping through.

I see. Thanks.

So, what I found was that I was not re-synchronizing the outlier flag output from the isoutlier function with the initial flag I used for sample points rather than background points. Mistake by me.

Thanks for your response.
