My variable name is Final_50000_run_1
Is there a way to extract the number 50000 and 1 out.
Thanks.

Yes, there is, but how did those numbers get there in the first place?

I saved it for different run of simulations in Fortran.

s='Final_50000_run_1'
regexp(s,'\d+','match','once')
If you want to extract all the numbers
regexp(s,'\d+','match')

Is this a variable name or a file name? If it is a variable name, I recommend you read question 1 in the Programming section of the FAQ for an explanation of why including data in your variable names is discouraged. If it is a file name, see Azzi's answer.
