Issue fprint outputting an xyz matrix to a file

Attempting to convert a txt file that has three columns and many rows of xyz coords.

I'll just paste what I have.

file1 =  fopen('test.txt' , 'w');

for m = 1:size(data,1)
    fprintf( 'Create vertex x %.f    y %.f    z %.f\n',[data(m,1);data(m,2);data(m,3)]);
    
end

'data' is the file I am attempting to pull data from. No output to test.txt, at the moment.

fid =  fopen('test.txt' , 'w');
fprintf(fid, 'Create vertex x %.2f    y %.2f    z %.2f\n',data.')
fclose(fid)

Why not simply use writematrix() or writetable(), it's much easier.
