Program Offering Guide
Release 2024b
Part Two: Deployment Rights
1. Deployment Rights for User Files
You may distribute or sublicense User Files without restriction, provided that
a principal purpose of the distribution or sublicense is not to replace or
replicate a Program or any part of a Program and you otherwise comply with the
general restrictions of the Software License Agreement and your License
Offering. "User Files" are MATLAB code files, Simulink model files, files
generated by RoadRunner Programs, MEX-files, MAT-files, VHDL-files,
Verilog-files, FIG-files or P-files that you create and that do not include any
code obtained from MATLAB code files, Simulink model files, MAT-files,
VHDL-files, Verilog-files, TLC-files, P-code, C/C++ files or other Source Code
files supplied with the Programs.
However, my quoting from the license agreement is not the same thing as a legal statement from Mathworks, so you need to contact Mathworks to obtain the legal statement.
(You were always going to need to contact Mathworks to get an official legal statement. Even if Mathworks had a banner page saying explicitly that it was okay, a banner page would not be the same as an offical legal statement.)
