See https://www.mathworks.com/help/matlab/datastore.html for the general solution.

Another approach is to fopen() the file, and textscan() using a repeat count (a number as the parameter after the format string) to control how many lines are read at a time; you would read a chunk, process it, go back to read another chunk, and so on.
