i am facing problem while trying to read data from xbee in matlab from 4 force sensors

%run('clean');
clear all;
close all;
delete(instrfindall);
s = serial('COM5'); %assigns the object s to serial port
s.ReadAsyncMode = 'continuous';
set(s, 'InputBufferSize',20); %number of bytes in inout buffer
set(s, 'BaudRate', 115200);
set(s,'Terminator','LF')
%clc;
x=0;
y=0;
z=0;
w=0;
fopen(s);
%opens the serial port
disp('Running');
while(true)
a =fscanf(s);%reads the data from the serial port and stores it to the matrix a
a1=str2num(a);
s1=a1(13);
x =[x s1];% Merging the value to an array, this is not very computationaly effective, as the array size is dynamic.
plot(s1,'Color','g');
axis auto;
grid on;
hold on;
drawnow;
s2=a1(15);
y =[y s2];
plot(s2,'Color','g');
axis auto;
grid on;
hold on;
drawnow;
s3=a1(17);
z =[z s3];
plot(s3,'Color','g');
axis auto;
grid on;
hold on;
drawnow;
s4=a1(19);
w =[w s4];
plot(s4,'Color','g');
axis auto;
grid on;
hold on;
drawnow;
a1=0; %Clear the buffer
fclose(s); %close the serial port
end

i am unable to get reliable data.my force data of each sensor lies in 13,15,17,19 bytes of each packet
