I'd use fprintf():
f = fopen('plot.txt', 'wt'); % 'wt' - write file, text mode
formspec = '%f %f\n'; % two values in a row (\n - line break)
% formspec = '%f %f %f\n'; % tree values in a row
for i = 1:3
a = rand;
b = rand;
fprintf(f, formspec, a,b);
end
fclose(f);
read about fprintf(), formatSpec. Look also for dlmwrite()

Just remove '\n' (line break)
fprintf(fileID,'%6.2e %12.8e ',output,T);
