最近不知为什么装了matlab6.5版本的和7.4版本的在用符号工具箱时都出现以下的错误，以前用的时候从来没出现过。
不知道是哪里有问题使得maple 初始化失败，请各位高手解决，万分感谢！！以下是超简单的一个命令，就出现问题，，在百度里搜了也有类似的问题，但没有人解决，苦恼啊！！！！

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~1\hp\LOCALS~1\Temp\matlab_crash_dump.528
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.
