Mac OS lion, and Matlab 2010a

Matlab 2010a (64 bit), does run on Lion OS, however there is a serious problem when trying to run a "TriscatteredInterp" command. Whenever Matlab reaches this command it causes a major crash that completely shuts down Matlab.

Troubleshooting my code shows that when my line containing "Fa=TriscatteredInterp(x,y,i)" is commented out the code runs, not giving the desired results of course due to this missing line, but Matlab does not shut down. I'm wondering if this could be an X11 issue? Since the crash so far seems to be very specific to this one command, I have no clue on how to fix it...........

If anyone knows a fix or a way to avoid using this TriScatteredInterp please let me know. I would be very grateful.

Thank You,

I have the same problem. I recently upgraded to Lion and did not use TriscatteredInterp before, so I would not know if the problem was there before. Right now it is a bother as Matlab always crashes when it reaches the TriScatteredInterp line.

Just tried it. Had no crash or anything what so ever. On Mac, I have found that overtime MatLab tends to crash for random reasons. Most of this is due to X11. I'd suggest simply re-installing.

This is a new install. I actually had this code working great many times on my old leopard OS, when I got a new mac(with Lion) and installed matlab, my code just won't run. Below is the piece of code that causes the crash

x=EndMapp_10_w2(1:20327,1);

y=EndMapp_10_w2(1:20327,2);

i=EndMapp_10_w2(1:20327,3);

x=(x-15);

y=(y-15);

i=(i*-1);

F=TriScatteredInterp(x,y,i); <----------Problem line

ti= -10:.05:15;

ta =-5:.05:10;

[qxa,qya]= meshgrid(ti,ta);

qza=F(qxa,qya);

mesh(qxa,qya,qza);

hold on;

plot3(x,y,i,'o')

Below is part of the error report if it helps.

Odd. The previous problem reports against Lion that I remember seeing, were of three different classes:

- crashes especially when doing various kinds of drawing, when using R2009a or earlier on Lion; I seem to recall someone mentioning TriScatteredInterp as a problem in this situation, but I cannot find proof of that now, so it might just be another one of my "brain farts".

- random crashes that were not very reproducible; there was a correlation with doing "heavy" computation, but not exclusively. The sort of problem one might almost expect from overheating. Or, since I gather Lion does not always allocate memory the same way, from subtle memory corruption that may show up randomly

- outright "MATLAB crashes almost immediately after startup, *always*" crashes.

I think yours might be the first report I have seen of a reproducible Lion-specific code-specific crash.

Unfortunately that _does_ imply that I have no idea what the solution might be... not enough information to correlate yet.

Interesting. I've not upgraded to Lion yet, but I do run MATLAB continuously, never shutting it down. It has not crashed in my memory at all, so at least several months.
