When I run the .exe outside matlab i have to press enter to close the dos window. It is only then that I can re-run the .exe for the next simulation. There is a note in the bottom loop where I am hoping to force the dos window to close... how do I script this?

end
%THIS IS WHERE I WANT TO CLOSE THE .EXE AFTER IT HAS FINISHED RUNNING. WHEN I RUN THE
%.EXE MANUALLY (OUTSIDE MATLAB, I HAVE TO PRESS ENTER TO CLOSE THE DOS WINDOW...BUT HOW DO
%I DO THIS IN MATLAB?? IN THIS BOTTOM LOOP I WANT TO RUN THE .EXE FOR EACH
%OF THE NUMBER OF SIMULATIONS, BUT THE .EXE WON'T RUN UNLESS THE DOS WINDOW
%IS CLOSED AT THE END OF EACH SIMULATION.
end
Many thanks!

I have provided this solution in several cases. You just need to have an empty line with a carriage return in that text file.

The correct way is:
CmdStr=[hydrus_exec, ' < ', CloseEXE];
system(CmdStr)

Use a .bat file instead -- that runs the desired executable and then ends with the 'exit' command.

You said it acts the same way from the command that you have to press a return to close the window...that shouldn't be; the window should be back at the command prompt. If it isn't, that implies to me the app is still expecting input.
If the command window is actually at the command prompt to type in "exit" to close it, then the batch file option will work -- the .bat/.cmd file content would simply be
yourexecutable command line first
exit
then you submit it instead of the command to just run the executable.

Actually, the line
[x, y]= dos(C:\\Users\jessi\Desktop\HydrusMC\H1D_CALC.exe);
can't work -- the argument to dos must be a character string and the above isn't...
Try
[status,res]=dos('C:\Users\jessi\Desktop\HydrusMC\H1D_CALC.exe');
instead -- and the executable should run in background without any command window visible at all.
I just tried a little Fortran test routine here as well as a form of your mistyped line above to see if the system command would do something funky like try to open a system prompt window but, as expected it errs on the bad syntax before getting that far, so this cannot be the exact code you're running to have a problem with.
>> [s,r]=dos(C:\\GCC\bin\tmp\testit.exe)
[s,r]=dos(C:\\GCC\bin\tmp\testit.exe)
Error: Invalid use of operator.
>>
That fails as would expect it to...
Let's run a little Fortran code -- it doesn't need any input files, but does execute w/o a visible window ever opening as should...
>> [s,r]=dos('C:\GCC\bin\tmp\testit.exe')
s =
0
r =
'zeros(6,4)

(I was checking out if new allocatable arrays were working in gfortran...)
I then modified the code to ask user for an input value -- that hangs the process awaiting that last input, but still doesn't open a visible window -- somewhat to my surprise, the default input stream is still attached through the MATLAB command window -- typing into it puts the response into the buffer for the app and lets it close successfully.
Think would have to see just how your executable runs and how it gets its input to have further insights on your issues.
Which OS we running under here?

Yeah, once figured out that it wasn't the command shell were needing to exit from but the application itself asking for user input, the whole problem changed drastically. @Fangjun Jiang presumed that from the git-go, I read the original post literally instead... :)
