hi i have a script like this
for i=1:10
parfor n=1:20
system(command(i,n));
end
end
I'd like the first for the first expected the end of all system Call and then continue with the cycle .

Does this mean, that you want to wait after the PARFOR loop until all system calls have been finished?

I'm not entirely clear what you mean by "I'd like the first for the first expected the end of all system Call and then continue with the cycle", but parfor does not guarantee that the iterations happen in any order.
If you'd like more control of what happens where, you might want to look at using spmd.
