smoothing unevenly spaced data

Hi guys,

I have two datasets. The first dataset is a time series that spans 10,000 years and it is evenly spaced in 20-year intervals. To remove some of the noise, I applied a 200-year running mean; pretty straightforward.

My second dataset is another time series that spans the same 10,000 years, however, these data are unevenly spaced. Ideally I would like to also apply a 200-year running mean to this dataset. I am at a complete loss on how to make this happen with an unevenly spaced dataset.

Any suggestions?

I'm also a pretty new Matlab user.

Thanks for your help.

when you say unevenly spaced, do you have the time information?

You can try resample them using some interpolation method:
