Is it possible to obtain the initial data after "smoothdata" function?

I am smoothing the data with smoothdata(data, 'movmedian'). Is there any way to obtain the initial data after the smoothing is done?

In general, no.
Smoothing involves filtering of some sort, and that removes the higher-frequency details of the original signal, and once that information is removed, it is never again available.
It is best to always save the original data before doing any sort of filtering or other pre-processing operation.

My pleasure!
‘It is best to always save the original data before doing any sort of filtering or other pre-processing operation.’
As I mentioned initially, keep a copy of the original data. Every filtering opearation I have encountered thus far has been irreversible.

Sure there is. I assume you're putting the smoothed results back into the initial arrays. Just make a copy of it before you smooth it so you'll still have them.
