I am synching up two data sets in Matlab and one of them started recording data 0.5 seconds before the other. How can I just disregard the first 0.5 seconds of data on my table across all 15 of my columns.

Do you want to automatically detect and disregard the different beginnings of your measurements or just do it once for your data?

You can find a lot of table operations here, including how to delete rows.

If you want to do it automatically it's also possible via detecting the beginning of numbers in your table columns, if the beginnings are for example NAN. But first tell me if this is needed.

I want it to automatically detect via the beginning number in colum 1. There are no NaN. The 0.05 seconds i mentioned before came from a time equation, so it is a duration not a number. I'm not sure if that has anything to do with being unable to disreard the appropriate rows for all columns.
