printing char(177) to text file

I want to put +/- char(177) between the numbers x & y and save the output as text file.

    x = [4 5 6];
    y = x*0.8;

Using sprintf, I get the output on the command window:

    sprintf(['%2.0f ' char(177)  ' %1.2f\n'], [x;y])

But when I am using

    fid = fopen('untitled.txt', 'w');
    fprintf(fid, ['%2.0f' char(177)  '%1.2f\n'], [x;y]);
    fclose(fid);

I don't get +/- between the numbers.

Your code works for me, Windows 7 (32-bit), R2011b , this is what the text file looks like after I run it:

 4±3.20
 5±4.00
 6±4.80

Have you tried opening the txt file in several text editor programs? Maybe the one you're using does not handle the ± character correctly.

Worked excelent for me win7 64-bit. What operating system do you use?

I am using R2014a on Mac OS X 10.9.2. And I am using TextEdit.

Can you see the ± symbol if you open the txt file in the Matlab editor?

[Rakesh]

no, I didn't see ± symbol when opened with Matlab editor too. However, it is working with previous ver. of Matlab in windows 7.
