Writing a function (.m executable) - how do I perform tasks on my workspace variables?

I have arrays called "Blah1", "Blah2", etc., in the workspace, and I want to write a function that finds the max of "Blah1", etc., and writes these max values to a text file.

I am not sure how to indicate in the .m file that I am performing the function on 'Blah." I'm good with the writing to a text file part.

Ideas?

Thanks,

Pocho

pass your blah matrix as an argument to your function:

yourfunction(blah1,blah2);
