Please watch the webinar for which this is the code. The first 40 min, as you correctly say, focuses on maximizing the available memory for MATLAB. The latter 25 min focuses on minimizing MATLAB's memory usage, processing a large data set in a few ways. BTW MATLAB's out of memory errors are not directly affected by available RAM.

Don't add the code at the very begining. Add if just before the first "if str2double..." line you insert.

This is definitely a nice tool. However, the folks who generate some of the data files I have have thrown a few curve balls. While I can reprocess the data from strings, I don't think it would be hard for you to add a few new features.
1. A new class of logical which translates strings of f or false or 0 or off to logical false (any case) and t or true or 1 or on to logical true.
2. A class which takes a set of string values that have a limited set of possible values and translates them into numbers. For example, there might be three different status types, e.g., standby, off, and on. We might like to put in numbers such as 0 for standby, 1 for off, and 2 for on. It would be handy to have textscantool do that translation rather than have us do the conversion later.
