Hello, I need your help to smooth the attached file. It is a two-column txt file. The first column is the frequency and the second is the amplitude. I would like to smooth the second column. Any kind of help is appreciated. Thank you.

Why not look on the file exchange? There are multiple tools there that claim to do Savitsky-Golay.
Even better, is to read the help/doc for smooth. It provides Savitsky-Golay as one option.

If you are asking for someone to write code for you, teaching you how to do Savistsky-Golay and providing complete code for it, that is arguably beyond the scope of Answers. (I for one won't do that.) Instead, you can find pseudo-code for it online. Then spend some time learning to do it in MATLAB from the algorithm.
