fprintf varaibles to a text file does not add cr/lf so text wraps

I'm writing varaibles to a text file but the written text wraps. Any idea what I'm doing wrong.

                %format output
                pl1 = sprintf(' Gen = %d ', GenNo);
                pl2 = sprintf(' Mem = %d ', GenMemNo); 
                pl3 = sprintf(' Try = %d ', TryNo); 
                pl4 = sprintf(' Samp = %d ', SampNo);
                pl5 = sprintf(' Path = ');
                pl6 = sprintf('%d ', OriginalPositions); 
                pl7 = sprintf(' Cost = %f ', cost); 
                pl8 = sprintf(' Var = ');
                pl9 = sprintf('%f ', inputvar);
                pl10 = sprintf(' Skew = ');
                pl11 = sprintf('%f ', inputskew);
                pl12 = sprintf(' Kurtosis = ');
                pl13 = sprintf('%f ', inputkurtosis);
                pl14 = sprintf(' Volts = ');
                pl15 = sprintf('%f ', volts);
                pl16 = sprintf(' AvInputs = ');
                pl17 = sprintf('%f ', AvInputs);
                pl18 = sprintf('\n ');

                %make a single string
                PrintLine = strcat(pl1,pl2,pl3,pl4,pl5,pl6,pl7,pl8,pl9,pl10,pl11,pl12,pl13,pl14,pl15,pl16,pl17,pl18);

                %write to screen & Log.txt
                %fprintf(PrintLine,'\r ');
                fprintf(fileID,PrintLine,'\r ');

thanks

Why not write directly to the file?

Answer 1

[Geoff Hayes]

Robert - if you want a line break for each "assignment", then you will need to add it after each numeric input. Try adding \n after each of your "values" as

 pl1 = sprintf(' Gen = %d\n', GenNo);
 pl2 = sprintf(' Mem = %d\n', GenMemNo); 
 pl3 = sprintf(' Try = %d\n', TryNo); 
 pl4 = sprintf(' Samp = %d\n', SampNo);
 pl5 = sprintf(' Path = ');
 pl6 = sprintf('%d\n', OriginalPositions); 
 pl7 = sprintf(' Cost = %f\n', cost); 
 pl8 = sprintf(' Var = ');
 pl9 = sprintf('%f\n', inputvar);
 pl10 = sprintf(' Skew = ');
 pl11 = sprintf('%f\n', inputskew);
 pl12 = sprintf(' Kurtosis = ');
 pl13 = sprintf('%f\n', inputkurtosis);
 pl14 = sprintf(' Volts = ');
 pl15 = sprintf('%f\n', volts);
 pl16 = sprintf(' AvInputs = ');
 pl17 = sprintf('%f\n', AvInputs);
 pl18 = sprintf('\n ');

The above, once written to file, should have the appropriate line breaks (carriage returns).

Whether it wraps or not depends on the application. In some it will be wrapped, in other not. If it's not wrapped in the application you want, then use both \n and \r:

fprintf('blah blah blah\r\n');

If that doesn't work, reverse them:

fprintf('blah blah blah\n\r');

I'm pretty sure one of those will work. You can do it with the sprintf's too.

ROBERT's "Answer" moved here:

Tried adding the \r\n & \n\r to both the sprintf & the fprintfs to no avail. I still get :

Try a simple case, like where you're just writing out 3 lines with 3 variables. Attach your code and output file so we can check it. Something like

fid = fopen('test.txt', 'wt');
fprintf(fid, 'This is line %d\n', 1);
fprintf(fid, 'This is line %d\n', 2);
fprintf(fid, 'This is line %d\n', 3);
fclose(fid);
msgbox('Done creating file');

For me, when I double click on the file and it opens in Notepad, the lines are on separate lines, so this works - no \r needed.

ARE YOU SURE you opened the file with 'wt' in the fopen() statement and not the 'w' option?
