I'm executing my c++ compiled program in MATLAB with dos('myprog.exe'). myprog produces some output that it is printed to the MATLAB command window only after myprog.exe finishes execution.
Is there a way to force MATLAB print the output when it is produced by myprog.exe and not at the end?
ANSWER Make sure that you are flushing correctly the output buffers in your c++ program. In my experience it sometimes helps to insert additional flushing commands (not just end of lines commands) to your code:
std::cout << std::endl;
NOTE You might also try to call your program like this:
[status,result] = dos('myprog.exe','-echo')
[status,result] = system('myprog.exe','-echo')
The matlab help says: "'echo' forces the output to the Command Window, even though it is also being assigned into a variable."
However this might not work because (again matlab help): "Console programs never execute in the background. Also, the MATLAB software always waits for the stdout pipe to close before continuing execution. " This means, that matlab might wait until your program finishes its execution before it shows you the console output. In that case there's nothing you can do about it.
