MATLAB: MATLAB ERROR I/O? IT IS A BUG

MATLABxlsread bug io

Why matlab gives me these errors only occasionally and only after a few minutes of processing? I believe that 92160800 is a generated file while matlab writing xls file.
ERROR:

Best Answer

Occasionally I get java errors like that. They've not been reproducible, and fortunately they're rare. (Sometimes it seems like they're more common if I'm sharing my desktop with someone over the LAN.) Restarting MATLAB seems to get rid of them.
