Best Answer

fileID = fopen('vp.txt','wt');
fprintf(fileID,'%.15g\n',V);
fclose(fileID);
Note that this will create 268435456 lines of about 17 characters each, for a total of approximately 4.25 gigabytes. You might prefer a different format though. For example would you prefer a comma separated file with 16384 columns per line? Would you prefer engineering notation?
