Hey guys, I'm new here. I'm having some issues with using the fprintf command. I want to use it to print actual words (NOT data, like a matrix) to a .txt file on my desktop. I've been all over the internet trying to figure out how to do this, but I can't seem to find anything regarding the fprintf command and opening things that aren't data sets.

Thanks in advance, Luke

在 MATLAB Online 中打开

fid=fopen('test.txt','w');
str='Actual textual thing, Once upon a time there was a princess trapped in the tower.';
fprintf(fid,'%s\n',str);
str='Same old story, at the end some guy freed the princes.';
fprintf(fid,'%s\n',str);
fclose(fid);

Specify the folder

folder = 'c:\users\Luke\Desktop'; % Wherever you want
fullFileName = fullfile(folder, 'test.txt');
fid = fopen(fullFileName, 'wt');

To pen in Notepad, use the system() function or winopen() function.

As image analyst said, either use:

winopen(fullPath_filename);

or use

system(['notepad ' fullPath_filename]);

and fullPath_filename is pretty much what you used in fopen function.

But What is it that you want to do? Do you want to convey a message to the user or something? May be there is another approach that could be more beneficial!
