How to wait for external executable to close?

Hey,

I'm using

system

command to run an external executable (Win 10 , MALTAB 2015a). In this exe the user required to perform a simple task of choosing files and afterwards the user will close the exe APP.

Can I somehow halt/pause MATLAB, till the user closes the APP?

If I try something like this:

system(myAppPath)
disp('moose')

I can see MATLAB is busy till the APP is closed, but it prints 'moose' nevertheless.

Please Help.

THANKS !!!

Hi Mark,

I can understand that you are trying to halt/pause MATLAB, till the MATLAB app executed by “system” function is not closed.

This can be achieved using the windows commands along with “system” function of MATLAB. Here’s an example doing the same:

sysCmd = 'start "" /wait "C:\Program Files\app1\application\app1.exe"'; 
system(sysCmd); 
disp('moose') 

Here, I have used to “/wait” to wait for the MATLAB application to close.

I hope this helps, thanks!
