Writing an array of numbers to serial port

Hi,

I have a device connected with the serial port. I intend to transfer an array of decimal numbers but am having some problems. I am able to transfer data successfully only if I use fwrite in a loop (i.e. one by one for each number). Is there a possibility to issue a single fwrite command for the whole array? P.S. I have tried several combinations of codes, but nothing seems to work :(

Following is the code which works:

data_hex = {'08', '0c', '05', '00', '04', '0a', '33', '33', '33', '33', '33', '33', '33', '33', '33', '00'}; % data in hexadecimal format
data_dec = hex2dec(data_hex); 

s = serial('COM9');
set(s,'BaudRate',5000000, 'Parity', 'none', 'DataBits', 8, 'StopBits', 1);
fopen(s);

      for i=1:16
          fwrite(s,data_dec(i,:));
      end

fclose(s); delete(s); clear

Ideally, I would like to have something like this:

fwrite(s, data_dec(1:end));

but this does not work. I get an acknowledgement on the serial device once the above 16 bytes are received. Thanks for the help!!!
