I want to smooth my noisy elevation vs distance data and also, [diff(Elevation)/diff(distance)] = grade; grade vs distance plot. I used smoothdata() command but the results are oversmoothed, it is over smoothing my data, hampel command does not work on my data ( no change in data). How do we adjust the smoothing factor for smoothdata or any other solution. Please let me know.

it would help (yourself) if you would share your code + data

You seem to know how to smooth your data in MATLAB, but are struggling with what the appropriate settings are. I'd suggest exploring the various options interactively by using the Smooth Data live task. It might be a simpler way to test out a variety of settings without having to have an in-depth knowlege of the underlying code.
Once you get the results you want, you can turn the live task into executable code.
