Serial communication through Matlab

Hi,

I am doing VHDL project using nexys2 board.

I need to read the sensor readings using matlab through serial communication.

My Code:

nexys = serial('COM1', 'BaudRate', 9600, 'Parity', 'odd', 'Terminator', '', 'Timeout', 1);
fopen(nexys);
s = 's';
    fwrite(nexys,s,'uchar');
     scan_s1 = fread(nexys,1,'uint16');

      t = 't';
  fprintf(t,'nexys')
       scan_s2 = fread(nexys,1,'uint16');

I am able to read the sensor values from nexys2 board. But the problem is that I geeting the sensor readings like

55352,45232 like this. But the maximum range of sensor is 400. It should not exceed this value.

Is this because continuous reading of data?

Can you please help me in solving the problem.

Thanks in advance Vivek Alaparthi
