How to use multiple cores

I use matlab to generate a series of input files and perform a simulation with each of those by an external program.

eval(sprintf('!%s "%s"','"[a bat file]"',[a matlab generated ini file]))

Using the line above matlab will wait until one simulation has ended before starting a new one. One simulation uses only one of 4 available cores. I would like to know if I can send 4 files into parallel simulation.

Thanks.

Hi,

try to use the & so that ML don't wait, saying:

eval(sprintf('!%s "%s" &','"[a bat file]"',[a matlab generated ini file]))

Or use Parallel Computing Toolbox to run several function in parallel.

I'd omit the EVAL and SPRINTF:

system(['"<a bat file>" "', <a matlab generated ini file>, '" &'])

Thank you both. All my simulations run simultaneous now.
