Hello everyone,

I’m not sure this is the correct category, so feel free to put it elsewhere.

I’m looking for a Julia package that implements a Savitzky-Golay filter or similar.  
I have FTIR spectroscopic data from which I would like remove the noise to some extend.  
I found the Spectra.jl package but I cannot use it due to a problem with Ipopt.

Is there any other package that implements this?

Many thanks,  
Olivier

It’s been a while since I’ve reached for this, but a few years ago when I needed one I found one in the un-registered QLab.jl: [https://github.com/BBN-Q/Qlab.jl/blob/master/src/SavitskyGolay.jl](https://github.com/BBN-Q/Qlab.jl/blob/master/src/SavitskyGolay.jl)

Jiahao then found it an interesting pedagogical case for a demonstration of the then-new `@generated` (nee stagedfunction) functionality and wrote up a tutorial: [Smoothing data with Julia’s @generated functions | by Jiahao Chen [he/him] / 陳家豪 [他] | Medium](https://medium.com/@acidflask/smoothing-data-with-julia-s-generated-functions-c80e240e05f3)

Not sure if there’s any more recent work, but at least that’s a starting point.

Thanks a lot for your quick answer!  
The implementation from Qlab did the job.

This discussion is now 6 years old. I just wanted to mention that we now have [SavitzkyGolay.jl](https://github.com/lnacquaroli/SavitzkyGolay.jl).
