Hello,
I was tring to run an exe from system in matlab and get the result before it gets stuck.
I tried [status,result]= system('name.exe < input.txt &' )and I did not get the results.
I am trying tic toc but it seems that it is not returning to Matlab from exe....
this is the part of the code.
cmd='xfoilP4.exe < xfoilinput.txt';
if toc(timer1)<waiting
[status,results]=system(cmd);
else
!taskkill -f -im xfoilP4.exe;
end

What is the purpos of:
if toc(timer1)<waiting
This not a loop and it does not wait until your command in the system() call is running. This is evaluated once before the system command is started. If the taskkill command is triggered, the system command did not run before.
What does "get the result before it gets stuck" mean? When the command does not finish, you do not get any results.
Please explain exactly again, what you want to achieve.

Thanks Jan for answering.
Actually I need to get some results from system command and analyze it...
cmd='xfoilP4.exe < xfoilinput.txt';
[status,results]=system(cmd);
the results are saving in results but sometimes it gets stuck in second line and it doesn't return to Matlab....so I want to close the cmd when it happens....
I used timer but it is not working.....
I saw this thread too:https://www.mathworks.com/matlabcentral/answers/44042-killing-exe-program-started-from-matlab
but it is closing by using PID and it is not relevent to me because I want to get the text file which is printed in the cmd and based on that taskkill the cmd...
I cannot change the script of xfoilP4.exe because it is predefined.

Not sure if this is what you want, but if you don't want the CMD window (console window) to show up while you run your .exe, you can use the -e option to mcc when you compile it. It will just show your GUI without the additional console window.

Try taskkill.
I don't think you can get anything from the console window before it exits since I believe MATLAB is just spinning it's wheels at that point waiting for the process to end. You might have to have your process write something to disk and have MATLAB open that file when it resumes.
