MATLAB R2015a and later is supported on Windows 10.
Earlier releases of MATLAB are not supported and are not guaranteed to work on Windows 10.
MATLAB 7.0 (release R14) is fourteen years old. From the System Requirements page the versions of Windows on which it is supported are Windows NT 4.0, Windows 2000, and Windows XP. [The release of Windows Vista was still about four years in the future when that release came out; Windows 10 was even further years away.] I would recommend you to upgrade your code to run in a more recent release. The Code Analyzer messages that you see in the Editor when you open your files may help you in identifying functions that have been removed since and what should replace them. If you find that you cannot identify a replacement after searching the Release Notes (the Release Notes for releases back to release R14SP2 are available on our website), please ask about a specific function or piece of functionality as an ML Answers post.
Hope this helps!
