Nimisha - what do you mean by popup saved text file? Do you want to open the MATLAB editor so that you can view the file, or some other editor, or ..?

If you just want to open the text file in the editor of your choice, then you can try using the system function. For example, if I wish to open a text file using TextEdit (on a Mac), I could execute the following statement in the MATLAB Command Window

 system(['open -a TextEdit ' fullfile(pwd,'myOutput.txt')])

Note that I use fullfile to build the full path to the text file named myOutput.txt. The complete string that I pass to system is

 ['open -a TextEdit ' fullfile(pwd,'myOutput.txt')]
 ans =
    open -a TextEdit /Users/geoff/matlab/testing2/myOutput.txt

Try the above and see what happens!

This works for me:

function myopen(str)
S = dir(sprintf('*%s*.txt',str));
cellfun(@winopen,{S.name});
end

and tested:

>> myopen('cat')

opens the file cat_dog_bird.txt using Notepad++ (being the default text editor on my computer (because it is much better than Notepad)).
