I have a standalone app in matlab. It gets a file name as an input and need to run this file. The file is on the same path as the standalone app.

thx, Mike.

You can use the -a option to compile additional files.

For instance, with this command you'll be able to call any .m file in your current directory from your standalone application:

mcc -m myscript.m -a *.m

  • Can i do it without compiling ? for example I can run files implicit like this: "!filename" but i can't find a way to give that command with incoming input. What i would like to do is: T = FileNameInputFromUser (M file) !T – michael zino Jul 08 '12 at 10:08
  • I don't understand what you're saying.... If you do like I said above, you can give any script name as an input and launch it from your stand alone application. If the script you want to launch did not exist at compile time, or if it has not been added with `-a`, you cannot execute it from your standalone application. – Oli Jul 08 '12 at 11:34
  • The problem is that new scripts are added, and i don't won't to compile each time the whole application. – michael zino Jul 08 '12 at 12:41
  • You cannot do it without recompiling. – Oli Jul 09 '12 at 10:36

It sounds like you're looking for the SYSTEM function. You can pass it any variable as a string: 

s = 'ls';  % use 'ls' for Mac/Unix, 'dir' for Windows
[status, result] = system(s);

Here status is the OS status code (0 means the program exited without error), and result is the output of the program:

>> status

status =

     0

>> result

result =

NB: If the program is not on your executable path, you may need to specify its absolute path:

s = '/usr/bin/ls';
[status, result] = system(s);

I think I asked exactly a similar question and could not get an answear.

Is it possible to execute compiled code both within and out of MATLAB environment?

I believe it is not possible as Mathworks doesn't want you to distribute a free Matlab interpreter. I wonder if one can compile two set of M files separately and run the second from the first as a workaround.
