Is it possible to restore all the variables from the previous session?

Unfortunately my MATLAB crashed at 46000 iterations while running a big loop with 64000 iterations. It took me one week to reach 46000 at iterations. Is it possible to restore all the variables from the previous session? Please suggest.

Unfortunately no.

It's up to you to regularly save the intermediate results and make you program able to warn start from where it left.

Sure. Just don't exit MATLAB. Or, save your results periodically. Why would you not do that on a long run that takes a week of run time????? Note that I have one problem I work on at night. I'll let my code run overnight while I sleep. It does frequent saves to a mat file. (Roughly once an hour.) I back up my computer too. Again, why not do these things?

If you don't do that, well, this is a learning experience for you.
