Restart variable from a middle point

Hi,

I have a for loop for a variable, let's call it X=linspace(a,b,c);

Now, imagine that I am calculating a variable M that depends on the values of X and suddenly Matlab stops.

How can I be sure that I store M until that point?

How can I restart the loop from the exact point that the calculation stopped?

Thanks in advance!

You could save M to a .mat file in every iteration of the loop. That will slow things down, however.

You could save the iteration number as well. That way you would know where it stopped and you could re-launch the loop from that point.

load dumpFile M X lastIteration 
for x=X(  lastIteration+1:numel(X)  )
  ...
end

Why do you expect Matlab to suddenly stop?

I am using a cluster and sometimes it is not realiable.

Therefore I need to be sure that if I have to make 5000 calculations and it stops after 3000, that I can restart it from that point.
