Hi all,

I want to execute a simple M script from the command line in a .BAT file. Right now I can open the .m file but then I have to hit "F5" to run and then close the editor. It's fine if Matlab is already up and running in a window.

Any ideas?

Thank you!

Under Unix type systems, you would use the '-r' flag followed by the quoted
text of the command to execute, such as

matlab -r 'doanalysis(5);quit'

I do not run the Windows version so I do not recall whether under Windows the
flag is still -r or if it changes to /R ... I think it remains -r .

Thank you Walter,

This does work (without the single quotes in dos). However it opens a new copy of Matlab each time I run it which is slow. I'd really like to run in my already-open Matlab session. Any ideas there?

Instead of a bat-file calling matlab why not let matlab call the batch commands, using SYSTEM or DOS, and its own m-files?

I'm trying to run a series of Matlab demonstration files from a presentation. Currently my best solution is to simply run the .m file directly, which opens the editor and I can just hit F5 to run and close the editor when it's finished.

matlab -r fileName();exit

Is good too, but slower since Matlab has to open and close each time it's called. So, I'm looking for the Holy Grail here.
