Issue fprint outputting an xyz matrix to a file

6 views (last 30 days)
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)]);
'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.')
Why not simply use writematrix() or writetable(), it's much easier.
