Faster sliding window statistics?
7 views (last 30 days)
I use slidefun to estimate statistics such as max, min, or RMS within a sliding window applied to a time series. It is very useful, but it can be slow if there are a lot of data points. Is there a faster sliding window routine out there? I didn't see any obvious candidates in the File Exchange, but would like to know if I missed any.

You can use these alternate functions. For mean, use conv(). For max, use imdilate(). For min use imerode(). Or the new moving stats functions Steve mentioned. They're all highly optimized. Whether they're faster than slidefun() is something you'll just have to check.
