采纳的回答： Jan

The matlab profile function displays an "attempted to access error" during a regular usage (R2009b).

??? Attempted to access o.lnos(340); index out of bounds because numel(o.lnos)=339.

Error in ==> mtree.mtree>mtree.lastone at 1794 ch = Pos - o.lnos(ln);

Error in ==> getcallinfo at 92 functionInfo.lastline = lastone(last(rootNode));

Error in ==> profview>makefilepage at 1104 strc = getcallinfo(fullName,'-v7.8');

Error in ==> profview at 71 s = makefilepage(profileInfo,idx, busyLineSortKeyStr2Num(busyLineSortKey));

Does anybody know how avoid this error?

Sorry about the previous (now deleted) comment, I had misunderstood the question.

I've seen this error, when I had edited an M-file during processing. Such things will confuse the profiler tremendously. It could be a problem also, when you run P-code, while the profiler tries to display the corresponding line of the M-file, but both files are different.

What do you find in the lines 339 and 340 of the concerned M-file?

Thanks Simon but I did not edit anything during during processing. I used the profiler to check an easy M-file with 332 lines. Nothing special. Even if I restart the system I'll get this error.
