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.

But then how could I restart it from a specific point?

[Matt J]

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?

[A_V_G]

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.
