Hello,
All of a sudden, warndlg() and msgbox() don't pass the string.
If I type
warndlg('My Warning','Title')
the dialog box has the correct title, but no warning icon and no message! Same with msgbox()
Any ideas?
Thanks.

The operating system (OS, so Windows, MacOS, Ubuntu, Arch, etc) provides an application program interface (API) to do things like determining what files are in a folder etc. One of the things the OS can do is make a window. That is why the documentation warns that the windows may look differently between operating systems.

Thanks Rik. Your comment was a good clue to just restart MATLAB.
