This error was detected while a MEX-file was running.  If the MEX-file

is not an official MathWorks

function, please examine its source code

for errors.  Please consult the External Interfaces Guide for information

on debugging MEX-files.

If it is an official MathWorks function, please

follow these steps in reporting this problem to The MathWorks so

that we have the best chance of correcting it:

1. Send this crash report to segv@mathworks.com for automated analysis.

For your convenience, this information has been recorded in:

C:DOCUME~1ADMINI~1LOCALS~1Tempmatlab_crash_dump.1108

2. Also, if the problem is reproducible, send the crash report to

support@mathworks.com along with:

- A specific list of steps that will reproduce the problem

- Any M, MEX, MDL or other files required to reproduce the problem

- Any error messages displayed prior to this crash report

A technical support engineer will contact you with further information.

Thank you for your assistance.  Please save your workspace and restart

MATLAB before continuing your work.
