Merge columns and export to a text file

Dear all,

I have array like that:

AB = [
    15.5000    4.3000
    13.9000    0.7000
    12.2000    6.9000
    11.5000    6.8000
    16.1000    0.7000
    17.1000   -0.6000
    ];

I need to convert it to the .txt (MS-DOS) in this form:

15.5000,4.3000
13.9000,0.7000
12.2000,6.9000
11.5000,6.8000
16.1000,0.7000
17.1000,-0.6000

But there are two problems;

Firstly when I try to merge them using this code:

AB = char(compose('%0.f,%0.f', AB));

I observe that the decimal part didn't include in. for instance, I have -0 incorrect values in the new AB.

Secondly, when I try to export them in a text file, I see some blank space after each row, for example:

" 15.5000,4.3000      "

But I don't want the " symbol and also blank spaces in the text file.

I tried everything I knew, but it's isn't accomplished well, So if anyone knows the solution, I would be grateful.

Best regards

Focusing on "I need to convert it to the .txt (MS-DOS) in this form:" in your question, this chunck of code might help you.

AB = [
    15.5000    4.3000
    13.9000    0.7000
    12.2000    6.9000
    11.5000    6.8000
    16.1000    0.7000
    17.1000   -0.6000
    ];

dlmwrite('test.txt',AB)

Attached the test.txt file for your reference.
