Instead of 'phase.txt' use the full file-name

dlmwrite('C:\A\b\data\phase.txt',phase)

so easy!

A more robust way is to use fullfile():

fullFileName = fullfile('C:\A\b\data', 'phase.txt');

It handles the proper direction of slashes (forward or backward) and will also figure out if it needs to append a trailing slash to the folder (which is the first argument) before it concatenates them. You might also want to call uigetdir() to let the user decide what folder to store the file in.
