How to call an exe with command line arguments

Hello All,
I am trying to use system command to call an exe file with command line argument. Please note that this exe file is developed by someone else, and i have no control of it.
I checked the user community, and found one solution to use redirection, but i think that is only applicable if the exe is scanning the user input with functions such as 'scanf' in C/C++.
I am looking for something as: system('a.exe arg1 arg2'). I hope i make my point clear.
Thanks,
Hailiang

It's unclear if the executable you are talking about accepts command line arguments. If it does, then the system command should work as you indicate. If the executable doesn't accept command line arguments, then there's not much else to do.

You can do just like that, right? system('dir') system('dir *.m')
If your argument is a variable, for example, arg2='*.txt', then system('dir arg2') won't work as you expect, you will need to come up with your command string and then run system(), like CommandStr=['dir ',arg2]; system(CommandStr);

In this scenario, does arg1 and arg2 need to be numbers (as in system('a.exe 8.5 7.3')) or can they be local variables ?

Here "arg1" and "arg2" must be strings. In
system('a.exe 8.5 7.3')
the executable "a" get the string '8.5' and '7.3' as inputs.
