Loop, function or memory problem: Loop variable in a function is limited automatically.

Hi to all,
I am processing 3D images. In one of the functions i wrote, "for" loop variable is limited to 262144 while it should not be. My loop is just like :
For i = 1 : 26214400 %( 1 : 512*512*100 ) .... end
In case it is a memory problem, i deleted some data to get more space on the memory my script uses but it did not work. The limit value does not change. I tried it on both uint8 and double data.
By the way i use Windows 7, i have 4 GB Memory. I strongly need help about this.
Thanks to all.
Ibrahim

So it works at the command line, it should work in the function. There is more to the story that we cannot see because we don't have the code....

What exactly does "stops and quit" mean? Did you use the debugger to find out, which line causes the break? Just insert a "if i == 262144, disp('catch'); end" and set a break point on the disp line. Then step through the code line by line. It is impossible for us to guess, which command in which line is responsible.

Hmm, something weird is going on. Can you verify that this works at the command line:
for ii = 1:512*512*100,jj = ii/2;end,jj*2==512*512*100
Also, in your loop is there a BREAK or RETURN statement anywhere?
