Is there any way of executing multiple DOS commands in one run?

Hi there,

I have multiple test cases (e.g. Test01, Test02, Test03...etc ) which need to excute in Windows DOS command prompt using 'swanrun' command. These files are generated from SWAN third generation wave model.

Currently I'm using ' dos [swanrun 'filename'] ' ; (e.g. dos [swanrun Test01]) to take the result outputs. So it will first complete Test01 and then come to Test02 and so on.

Is there any possibility to run these files parallely in matlab?(as we can run these cases using multiple windows command prompts) and in Matlab, is there any facility available to parallel processing?

Thank you

Append a '&' to the string provided to dos() (or to system(), which does not depend on the platform):

for k = 1:5
  filename = sprintf('Test%02d', k);
  system(['swanrun ', filename, ' &'])
end

any suggestions for the follwoing code? it does not work.

cmd_H01 = 'H1_L01.exe'; % Path of H1_L01.exe

cmd_H02 = 'H1_L02.exe'; % Path of H1_L02.exe

system('cmd_H01; cmd_H02');

system('cmd_H01 & cmd_H02');

cmd_H01 = 'H1_L01.exe'; % Path of H1_L01.exe
cmd_H02 = 'H1_L02.exe'; % Path of H1_L02.exe
system([cmd_H01 ' & ' cmd_H02]);
