When MATLAB crashes, up to three log files may be generated with the following names:
matlab_crash_dump.XXXX
java.log.XXXX
hs_error_pidXXXX.log
The filenames will not have XXXX in them, but rather a number representing the process ID. For example, you might see crash dumps named "matlab_crash_dump.3944," "java.log.3944," and "hs_error_pid3944".
If MATLAB is started with the '-logfile' option, a separate crash file is not created. Instead, the crash information is written to the end of the log file specified by the '-logfile' option.You can also manually locate for the crash dumps:
Windows
On Windows these files are located in the folder where the operating system stores temporary files. To open your temp directory, enter the following into the search field in your Start Menu/Start Screen/Taskbar:
%temp%
or manually navigate to
C:\Users\%username%\AppData\Local\Temp
Linux
On Linux, crash dumps are saved to your home folder. Type "cd ~" or "cd /home/$USER/" to navigate to your home folder.
Mac
On Mac, crash dumps are saved to your home folder. From the Finder, click the "Go" menu and select "Home" to open your Home folder.
