How to run MATLAB files in batch mode (or as a batch process). Guide request.

Hello, my problem can likely be resolved with a simple guide. Unfortunately I simply haven't been able to find one. I've only used MATLAB in interactive mode and have no experience with running anything in batch mode or as a batch proccess. So that said, could someone point me to a guide (or two, reading more never hurts) that could walk me through the steps I need to take?

matlab -r "statement"
The statement should be the bit of MATLAB code you want to execute.
I recommend
matlab -noFigureWindows -r "try; run('C:\Path\To\YourScriptName.m'); catch; end; quit"
To be safe, YourScriptName.m should have instructions to cd() to the directory it is to work in.
run() cannot be used with functions, only with scripts. For functions,
matlab -noFigureWindows -r "try; cd('C:\Path\To\'); YourFunctionName(); catch; end; quit"
The above commands could be put into a .bat file, and could be invoked from any directory (because the mini-script changes directory.)

The name of the guide is the online documentation. It includes many examples and demos. Your question puzzles me
- what do you understand with "batch"?
- do you know "function" and "script" in Matlab?
Search for "Programming Fundamentals" and "Working with Functions in Files" in the online documentation.
See: Demos | Getting Started | Writing a MATLAB Program (5 min, 45 sec)
If you want to invoke Matlab from a "dos batch file" see:

matlab helpOption
matlab -automation

"batch" can also refer to a mode for use with distributed computing.
Be sure to see the -r switch (or is it /r on Windows?) to indicate which .m file to begin.

hey Alfonso,
I'm not sure if this what you're after. Read the first part of it (don't worry about the grid part)

Hi Everyone ! I have several .m files which take a lot of time to execute, I intend to execute sequentially those .m files while saving the workspace variables for each m-file. Do I need to write a batch file to do this while I am away and I can run the batch file which calls the m-files sequentially. Can anyone guide me how to do that for simple m-files . Will appreciate any help in this regard Maqsood
