Say I have a single stream of data (vector) that has sections where I want different filter window lengths. For instance, I want specify a vector of window lengths equal to the length of my data, how? I don't want to break up my data stream.
The only option I see is to somehow dynamically scale the data using interpolation and then use a smoothdata with a fixed window.

Yea I know how to smooth with N fixed. I was hoping I might not have to iterate through the entire array (this might be clumsy with large data sets). I would also like access to the gaussian method.

For some more context, this has to do with changing day length over the year. Say sunrise-to-sunset = 1, else = 0 for all days of the year. If all days were half day/half night, I could use a fixed window of 1440 minutes and get a nice curve/oscillation. But imagine day length minimizes, to just small notch, then N=1440 is not really an accurate—my thoughts are I would want to decrease N based on day length here so my curve captures the shape of either long or short days in a similar manner.

In brief, I'm just running through progressively smaller filters and creating a smoothed binary gate depending on if the filter applies to a specific section of the data stream.

Thanks for taking a peek, I think it might be too niche for a general answer. Cheers!
