If you have questions, comments, and/or feedback regarding theTall Arrays in Action video, or using MATLAB with big data in general, please post them here, and I will respond to you (or find someone to respond =P) as soon as I can!

P.S. Heather Gorr has a very similar video locatedhere. This Answers entry is intended for the first video, but feel free to ask away about tall arrays in general =)
Is there a way to add new rows of data to an existing tall array? Suppose I have a large data set, stored as a tall array with the write function, and new data are coming in. Can I then add the new data to the existing data set? If so, how?
Hi Michel, at this time the only way to add new data to a tall array is to recreate the tall array from a datastore containing both the existing data and new data. You could use the tall array write method to achieve this:
% Suppose at the start you have initial data, write it out as so:
write('MyFolder01', tX1);
% Suppose you have some new data at a later time, write it out like so:
write('MyFolder02', tX2);
% Then to analyse all the data thus far, specify both folders as
