Sampling and Filtering Table Data

How do I sample data from a table that I read from a file? Also i have to ensure aliasing does not occur. Morever, how can I apply filters to remove abnormalities? Is it possible to get back the main data from sampled data?

hi

it would be helpful to share your data and code if you have one , and tell us more precisely what you want to do on your data

Well the data is UCI wall following robot navigation dataset.

I want the matlab code to figure out the correlation, sample data with any technique(while ensuring aliasing does not occur), filter data to reduce abnormalities and then restore the data to original from sampled form.

I hope you can help me in this

Presumably you would have a timetable. If you have the Signal Processing Tbx, you should look at resample.
