How to combine sprintf and fprintf

Hello everyone,

Here's what I want to do :

      -I use fprintf to print a sentence with new lines inside, for example:
               text=sprintf('%s \n %s',sentence1,sentence2);
      -Then I want to save it in a .txt file with this :
               file=fopen(sprintf('%s%s%s',filepath,filename,'.txt'),'w');
               fprintf(file,'%s',text);

It displays what I wrote except the new line : I have in my file sentence1sentence2

Any idea on how to fix this problem?

Thank you!

A more stable method to create the file name due to the consideration of file separators:

fopen(fullfile(filepath, [filename, '.txt']))

How do you test if there is no newline? You write the file in binary mode, such that CHAR(10) is used as line break. All editors I know can handle this correctly, but not the standard "Editor" of Windows. So please open the file in WordPad or Matlab's editor also.

I leave it up to others to mention the 'wt' method for fopen, because I usually warn for the eventually unexpected side-effects.

Ok, when I open it with WordPad I have the new line!

But I don't really understand why the editor of Windows canno't recognize that there's a new line.

Thank you!
