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~1\ADMINI~1.KUN\LOCALS~1\Temp\matlab_crash_dump.2784 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.

>看样子是maple工具箱的问题，我在另一个论坛提问，有位网友让我重装工具箱试试，可是重装后问题照旧，请问各位有什么办法吗？谢谢！

不行的话重装matlab吧
