This era focused heavily on Simulink , introducing tools for implementing LTE-A downlink physical layers and supporting broader engineering requirements for 4G communications.
Files written in R2009 (such as .m and .mat v7 files) are generally readable in newer versions, but code using newer objects like Neural Networks or specific image types (like JPEG 2000) may not be backwards compatible if moved back to a 2009 environment.

While modern versions use table() objects, R2009 relied on xlsread() for Excel files and matrix-based data manipulation. Users often used regexp or fileread to process text files because newer high-level functions like readtable did not yet exist. This era focused heavily on Simulink , introducing
