writetable or dlmwrite to save an array as a txt file

Hello community

I need to save a txt file like this one

 1  -26.2  -31.7
 2  -27.1  -33.9
 3  -25.5  -30.2
 4  -24.4  -30.8

starting from this array

  1.0000  -26.2000  -31.7000
  2.0000  -27.1000  -33.9000
  3.0000  -25.5000  -30.2000
  4.0000  -24.4000  -30.8000

writetable seems to have limitations. Is there any other way?

Thank you!

Here's one way:

M = [
    1.0000  -26.2000  -31.7000
    2.0000  -27.1000  -33.9000
    3.0000  -25.5000  -30.2000
    4.0000  -24.4000  -30.8000
    ];
filename = 'your_file.txt';

% write the file:
fid = fopen(filename,'w');
fprintf(fid,'%2d  %.1f  %.1f\n',M.');
fclose(fid);

% check the result:
type(filename)

 1  -26.2  -31.7
 2  -27.1  -33.9
 3  -25.5  -30.2
 4  -24.4  -30.8

M = [
    1.0000  -26.2000  -31.7000
    2.0000  -27.1000  -33.9000
    3.0000  -25.5000  -30.2000
    4.0000  -24.4000  -30.8000
    ];

writematrix(M, 'your_file.txt', 'delimiter', ' ');

type your_file.txt

1 -26.2 -31.7
2 -27.1 -33.9
3 -25.5 -30.2
4 -24.4 -30.8
