MATLAB: Wait until batch Cygwin simulataion finish

dos wait

I am running batch file from matlab in a loop form. How can I make the matlab loop wait until the batch execution finished?

for k=1:1:3
      dos('mrun.bat');
end

If the .bat file does not start any interactive processes and does not use "&" to create a new process, then dos() will automatically wait for it to finish.

If the .bat file starts an interactive process (for example it might start up Excell) then you can loop testing to see if the processes are still alive; see this File Exchange Contribution or you can use tasklist

MATLAB: Is the execution of the batch file stopped after running the MCC command on Windows in MATLAB Compiler 4.16 (R2011b)

When MCC is invoked from batch file or from system prompt, it invokes mcc.bat as opposed to mcc.exe(from MATLAB). You can verify by checking "where mcc" on your system prompt, you will see it gets from mcc.bat.

So in that case, there is a batch file calling another batch file when MCC is called like in the example. Usually when batch file calls another batch file directly like in the example, they don't handle back the control to the called batch file. Thus one will see the behavior we observed. In that case, one can use CALL on the BATCH file one is calling inside the batch file. For example, the example code can be changed like below and one will observe changes:

echo Start compiling
call mcc -m test.m -v
echo Compiling done
pause

MATLAB: How to force MATLAB 7.9 (R2009b) to wait for an EXE file to complete before continuing with the MATLAB script or function

You can use MATLAB to check if a particular process is running on the system and make MATLAB wait until this process is closed.

Here is a simple example that uses a DOS function SLEEP as the executable. Attached are two files testRun.m and isprocess.m. You will need the isprocess.m file to check the system processes for a particular exe.

testRun shows a sample:

% Do some tasks
% Call sleep.exe for 30 seconds
% (sleep makes dos "idle" for the given time, simulating if the exe were running)
!sleep 30 &
% MATLAB will continue execution once EXE is launched
disp('MATLAB continues after calling EXE')
% Check to see if the EXE process exists
flag = true;
while flag
     disp('EXE still running');   
     flag = isprocess('sleep.exe'); % isprocess is the function attached. Place it on the MATLAB path.
     pause(1) % check every 1 second
end
disp('EXE Done')
disp('continuing with MATLAB script')
