Upon startup, if MATLAB® detects an error log generated by a serious problem during the previous session, an Error Log Reporter prompts you to email the log to MathWorks® for analysis. The error log contains the stack trace and information about the MATLAB software configuration. If the problem occurs repeatedly, make note of what seems to cause it, look for information about it in the MathWorks Bug Reports database, and if the problem is reproducible, submit a Service Request via http://www.mathworks.com/support/contact_us/ts/help_request_1.html.
There are some situations where the Error Log Reporter will not open, for example, when you start MATLAB with a -r option or run in deployed mode. It also will not open if you selected the option to never send error reports the last time the Error Log Reporter opened. If you experience abnormal termination but do not see the Error Log Reporter on subsequent startups, you can instead email the reports.
Send email to firstname.lastname@example.org with this file attached: C:\Temp\matlab_crash_dump.####. After you send the log file, delete it or move it to another location. If you do not delete the log file, the Error Log Reporter can detect it on the next startup and prompt you to send it, even though you already emailed it.
