I'm trying to write data that I have in a matrix to a .txt or .csv file. I have data in a 250x2 matrix, and would simply like to be able to write this out to a file of my choice, say 'data.txt' or something like that. Is there an easy way to do this?

compose the destination folder dynamically:
root = 'C:\User\Me\Documents\';
fname = 'filename.txt';
dlmwrite([root fname]...)

Or use fullfile
fullFileName = fullfile(root, fname);
fullfile takes care of creating the correct filename regardless of whether root has a trailing slash or not.
or sprintf
fullFileName = sprintf('%s/%s', root, fname);
