Thread Subject: debug startup error

my Matlab reports an error at startup,
"[Fatal Error] :-1:-1: Premature end of file."

I have removed user defined startup.m file. But the error
still comes up. Anyone knows how to debug such an error?

Thank for help.

You might also check pathdef.m to see if there is any
corruption.

Also, I don't know if your Matlab command window still
opens up. Another file to look into is matlabrc.m, which
is related to the Matlab startup.

Thanks for reply. I have checked all files in the
toolbox\local folder including pathdef.m and matlabrc.m.
Nothing is wrong there. Any other place I should check?

Is your Matlab command window still up? Would lasterr()
provide some extra info? Otherwise, I have no other ideas.
The error seems pretty serious. Do you recall anything you
did recently that could corrupt some files related to
Matlab?

Yes, the command window still up, but lasterr does not give
any information except ''.

I managed to make a breakpoint in matlabrc.m. But the error
already happens before the matlabrc. Do you know what is
executed before matlabrc?

I also tried to search the string ':-1:-1' using wingrep
for all *.m files in the disk. But I cannot find any file.
Any othe ideas?

The other thing to check might be the license.dat. But I
don't think there is much lead on that.

Is there anything that you can think of that might leads
to this fatal error, something you did on your computer
system, files, install/uninstall?

I did a search on the Mathworks support
website. "Premature end of file" leads to an article about
QuickTime. I don't know if it is anything related.

Interesting. I googled "Fatal error premature end of file"
and got a few leads related to Java and XML. You might
want to do the same and see if anything rings a bell.

The only thing I can think about is that I quited matlab
when a m-file was not completed some days ago. But, this
error repeatedly comes up even I have completed the file.
If the error is related to this file, then I think this is
a bug related to mlint, which uses java virtual machine.

I have the same error message at the start-up. Matlan runs fine. I got this error after I terminated (kill it in windows task manager) a command of reading a big data file.
Don't know how to get rid of this message. Any ideas?

I had the same problem, but solved it using the solution in the link usefully referenced by fong ming hooi (http://www.mathworks.de/matlabcentral/newsreader/view_thread/242579). Specifically http://www.mathworks.co.kr/support/solutions/en/data/1-63Z0WN/index.html?product=ML&solution=1-63Z0WN
