Run multiple exe at same time

Dear all,

I would like to know if MATLAB is able to run the multiple exe simultaneously. If yes, how to run it?

Answer 1

Yes, you can use "&" to return control to MATLAB immediately after the exe starts. Then you can immediately run an exe again. For instance:

!excel.exe &
!excel.exe &

That would start two instances of Excel.

Thanks for your suggestion.

Do you mean to use the "!" + "**.exe"+ "&" ?

[Voss]

You can construct the command using string concatentation, yes.

Or you can use system() to run the exe with " &" on the end.

the code does not work. Any suggestions?

cmd_H01 = 'H1_L01.exe'; % Path of hh-1D.exe

cmd_H02 = 'H1_L02.exe'; % Path of hh-1D.exe

system('cmd_H01; cmd_H02');

[Walter Roberson]

system(strjoin({cmd_H01, cmd_H02}, ';'))

[xiaohuo]

system([cmd01,'&',cmd02]);

This works well!

Thanks!

As .exe are specific to Windows, you could consider using .NET System.Diagonstics.Process to create the processes and control them.

Would you please give an example? for instance, "test66.exe", how to run this exe?

for i=1:6

cmd_H1D = 'test66.exe';

system(cmd_H1D);

end
