Hello,
There is a large tabular data in txt, e.g. 10000 rows and 20 columns.
I would like to read in matlab environment only the last 100 rows instead reading whole file and taking from it last 100. I am aiming at speeding up Matlab, because it takes too long when every time reading the tabular data which is actually increasing (at the beginning the data is not massive).
