How to store real time loop data in MATLAB?

I have the problem with the real time loop data. I can't store it because it only stores the last number that created with for loop. The code is seen below

clear all;
close all;
clc;

s = serial('COM8','BaudRate',9600);
set(s,'DataBits',8);
set(s,'StopBits',1);
s.ReadAsyncMode='continuous';
readasync=(s);
y1=cell(1,100);
y1_1=cell(1,100);
y1_2=zeros(100,1);
y2=0;
y3=0;
y5=0;
y_est=zeros(100,1);
v_est=0;
x=0;
i=0;
j=1;
fopen(s);

for x=1:100
  y=fscanf(s);
  d=length(y);
  if d==8
      l=y(1); m=y(7);
      if l=='B' && m=='E'
      y1 = mat2cell(y, ones(size(y,1),1), size(y,2));
      y1 = strrep(y1, 'B', '');
      y1_1= strrep(y1, 'E', '');
      y1_2 = cellfun(@str2num, y1_1)
      end
  end
  %Encoder milimeter
  y1{x}=magic(x);
  y1_1{x}=magic(x);
  y1_2(x,1)=x*(1);
  y2 = y1_2/360;
  figure(1);
  subplot(2,1,1);plot(x,y2,'*');
  title('Encoder Milimeter');
  xlabel('x-axis');ylabel('y-axis');
  hold on;
  %grid on;
end

How I can store the real-time looping data?

Thank you,

Note: I'm using ALtera for data acqusition.

What is s? Which variable you want to save?

[Setiawan Putra Hendratno]

s=serial('COM8','BaudRate',9600);

I want to save the encoder's value (y2) in milimeter. But, It has only one last data to save.

s = serial('COM8','BaudRate',9600);
set(s,'DataBits',8);
set(s,'StopBits',1);
s.ReadAsyncMode='continuous';
readasync=(s);
y1=cell(1,100);
y1_1=cell(1,100);
y1_2=zeros(100,1);
y2=0;
y3=0;
y5=0;
y_est=zeros(100,1);
v_est=0;
x=0;
i=0;
j=1;
fopen(s);
iwant = cell(100,1) ;
for x=1:100
  y=fscanf(s);
  d=length(y);
  if d==8
      l=y(1); m=y(7);
      if l=='B' && m=='E'
      y1 = mat2cell(y, ones(size(y,1),1), size(y,2));
      y1 = strrep(y1, 'B', '');
      y1_1= strrep(y1, 'E', '');
      y1_2 = cellfun(@str2num, y1_1)
      end
  end
  %Encoder milimeter
  y1{x}=magic(x);
  y1_1{x}=magic(x);
  y1_2(x,1)=x*(1);
  y2 = y1_2/360;
  iwant{x} = y2 ;
  figure(1);
  subplot(2,1,1);plot(x,y2,'*');
  title('Encoder Milimeter');
  xlabel('x-axis');ylabel('y-axis');
  hold on;
  %grid on;
end

iwant is a cell. You can access it using iwant{1},iwant{2}...

when I checked the data of y1_2, the data is claimed as double, not cell. In this case, I have to change the data into cell again, right?

[KSSV]

I think your y2 is a array. So I am not sure of it's length, so better put them into a cell.

Okay, thanks for your sharing code.
