- Take a look in that directory and see if the file is there.
- Check the permissions on the directory and the file to make sure you can read and write there.
- Move the file aside (e.g. mv matlab_metadata.mat matlab_metadata.mat.old) and try to open matlabpool again. You might see a warning like "file is missing ... re-creating it")
- Running validation might tell you more.
can't do parallel computing

I have a problem with parallel computing. I can't open matlabpool. When I type matlabpool 6, I got the following.
Can somebody take a look? Thanks in advance.
