Segmentation violation detected 是什么错误？
我在使用ＭＡＴＬＡＢ的符号运算时，对一函数进行定积分时出现以下错误提示．程序中断，不得继续．请各们帮忙分析之：------------------------------------------------------------------------

Stack Trace:
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\wangyb\LOCALS~1\Temp\matlab_crash_dump.2680
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.

最好把M文件贴上来。 syms x y a b w0 k n E1 E A H hv D q w f1 f2 f3 f4 f5 f6 f7
%D=E*h^3/12/(1-v^2)
w=w0/(pi/2-1)*(cos((x^2/a^2+y^2/b^2)*pi/2)+pi/2*(x^2/a^2+y^2/b^2-1))
f1=D*(diff(w,x,4)+2*diff(diff(w,x,2),y,2)+diff(w,y,4))
f1=simple(f1)
f2=k*w-q
f3=f1+f2
f4=f3*w/w0*(pi/2-1)
f5=int(int(f4,x,-a*sqrt(1-y^2/b^2),a*sqrt(1-y^2/b^2)),y,-b,b)
%f5=4*int(int(f4,x,0,a*sqrt(1-y^2/b^2)),y,0,b)
%f5=4*int(int(f3,x,0,a*sqrt(1-y^2/b^2)),y,0,b)
%simple(f5)
%pretty(ans)
%f6=solve(f3,w0) 我的提示：
Warning: Explicit integral could not be found.
应该是和被积分函数有关，不能做定积分。
