Hello everybody !
I noticed one thing which i don't understand : I made a batch file to execute a finite element method software and when I execute it manually, the calculation lasts 5 minutes. When I use the dos (or system) function in Matlab to execute the same batch file, the calculating time is 25 minutes !!
I would like to understand why and if a solution exists.
Thank you !

Are you rrunning out of system memory when matlab is open?
How man processors do you have?
Was your computer doing anything else at the same time?
Is it repeatable? i.e. does it consistently take 5 times longer?

what do you get if you type:
tic; system ( 'sleep 3' ); toc
