Running EXE files parallel

I have written the following line for calling the cysim_solver. exe file

if 0, system(strcat('sim/CySim_solver sim/CySim', ' > out')); else system(strcat('sim\CySim_solver.exe sim\CySim', ' > out')); end;

I want cysim_solver.exe to use all the 4 processors in my PC. Can you tell me how I can do it ?

With parallel computing toolbox:

parfor ii = 1:n
  system(sprintf('foo.exe -%i',ii))
end

You have to build up the system call based on the iteration.

Sorry again for the late response for the question I tried the parfor in the comment above and I get the following message

The process cannot access the file because it is being used by another process. 'Cysim_solver.exe' is not recognized as an internal or external command, operable program or batch file.

My objective is to get a faster output so I would like to use multiple cores. Can this be done using matlab parallel tool box
