Is there a way to just call matlab from a dos command, pass it a .m file, have it execute that .m file and exit quitely, possibly only returning a completion status?

There are a number of options you can pass. In your case, I think you would use -minimize, -nosplash and the path to the m-file you wanted to run.
All the options are documented here:

The completion status can be a bit tricky, as I'm not 100% sure that %ERRORLEVEL% will be set correctly if there's an error in your program, since MATLAB may have "exited correctly". You would need to experiment with that, but it should be easy to test.

Note: when you use the "-r" option, if your .m file does not already include "quit" or "exit", you should add that to the command line; for example,
matlab -r "mymfile;quit"

i don't seem to be able to prevent the command window from showing up. My command line:
matlab -nosplash -nodesktop -noFigureWindows -automation -r "callMagic;quit"

scratch my last comment - the command window only shows up because there was an error in my callMagic. there ought to be a way to suppress that as well, but it is not a showstopper for me. thank you all again.
