-% An example of how you shouldn't write data:
-%
-% for i = 1:length(freq)
-%    fprintf(save_to_file_handle,'%s',sprintf('%f',freq(i)));
-%    fprintf(save_to_file_handle,'\t');
-%    fprintf(save_to_file_handle,'%s',sprintf('%f',trA(i)));
-%    fprintf(save_to_file_handle,'\t');
-%    fprintf(save_to_file_handle,'%s',sprintf('%f',trB(i)));
-%    fprintf(save_to_file_handle,'\n');
-% end;
-%
-% This is much faster:
-data = [freq; trA; trB; trC;];
-fprintf(save_to_file_handle,'%f\t%f\t%f\t%f\r\n',data);
-% Close the file
-fclose(save_to_file_handle);
-disp('Done');
-
-% Close all opened files
-fclose('all');
