[求助]问int函数出现的问题?

雨路的梦

输入int(func,yy,-r,r)的时候出现如下错误，请高手指点，十分感激！！
其中func等于：

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\陆汝华\LOCALS~1\Temp\matlab_crash_dump.4084

  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.
