fid = fopen('gc_test.txt', 'wt');
fprintf(fid, '%4.4f\n', [Vb;pH]); 
fclose(fid);

If you want two columns

Vb=[1;2;3];
pH=[4;5;6];
fid = fopen('gc_test.txt', 'wt');
fprintf(fid, '%4.4f   %4.4f\n',[Vb,pH]' ); 
fclose(fid);

thanks for your time Azzi, tried that but it still only in one row but alternates between each of the array

0.0500 Vb
0.7557 pH
0.1000 Vb
1.0567 pH
0.1500 Vb
1.2329 ph

i would like it to be like this

Vb       pH
0.0500   0.7557

A={0.0500  0.7557 ;0.1000  1.0567}
header={'Vb' 'pH'}
fid = fopen('gc_test.txt', 'wt');
fprintf(fid,'%s          %s\n',header{:})
fprintf(fid, '%4.4f    %4.4f\n',A{:} ); 
fclose(fid);
