I have a dataset that is drifting a bit in time. Is there a way in matlab to counter it? I have data that changes amplitude at times but the overal line us drifting downwards or upwards. I like to remove the drift since it's not the important to my data.

I would use the detrend function. There is a similar function (by the same name) for ‘timeseries’ objects. There are a number of other options as well.
