Hi,
I am running an external .exe file that returns something to the matlab command line once it has finished. I would like to use this in an optimization but currently the enter key needs to be pressed in the command line in order for the .exe to close and then for the matlab code to continue.
Here's how i'm calling the .exe: eval(['!program',tempfilename]);
Is there a way I can continue after it has finished? I have tried a timer and the java robot, but neither seem to work.
Thanks,

You will have to find a way to get your program to work without interaction.
Also, why aren't you using system instead of eval?

You can use system() function to pass the command (as a string) without the "!" symbol. If using unix OS, you can pipe (with the | character) a newline character entry ( with echo -e '\n') to a program. System will wait until both commands are completed. Note: the double apostrophes around \n are needed as escape characters and print an apostrophe.
system(['echo -e ''\n'' | ',some_exe_str]);
Not sure if using Windows...

Or with the double quote:
status = system( [ 'echo. | program "' tempfilename '"'] );

Thanks all, working perfectly now! - also the period is not necessary, thanks for pointing that out.
