Hello, Is there any way that i can lock my models that i create in MATLAB/Simulink? I want to protect my Matlab/Simulink files with password in order to avoid any modifications from other peoples. Thanks

depends on what you're doing and how you're giving them to people. Do you want them to still be able to read them? if not at least for m files you can pcode them http://www.mathworks.com/help/matlab/matlab_prog/protect-your-source-code.html. I do not know if simulink has something similar but now you know what to search for. I do not know how to keep them in a readable format and still protected. note that its not password protected just obfuscated. you'll need to keep the source

Otherwise if you could compile them with matlab's application compiler.

Also the obfuscation of pcode can be mostly reverse; someone has written a tool for that purpose.
