MATLAB offers lots of ways to read text files, including textscan, readtable, fileread or low-level I/O (fread). However, when you deal with larger files (note that 43 mb is not even close to being large, maybe 2 GB or larger), datastore or memmapfile are quite useful. For start, you can check
doc tabularTextDatastore
