请帮我看一个程序，看这个是什么意思，关于卡尔曼滤波的

elvachavie

% modeling data

% sample number N=200 points

% sample time T=0.1s

t=0:0.1:20-0.1;

T=0.1;
% sample time

v=0.5;
% initial velocity

y=ones(1,200);

y(1)=0;

for n=2:200;

y(n)=y(n-1)+v*T;

end

figure(1);

plot(t,y,'-');

axis([0 20 0 20]);

xlabel('time');

ylabel('yp position');

title('the initial track of movement');

% add white gauss noise

a=0.5*randn(1,200);

s=y+a;
%data+noise

figure(2);

plot(t,s,'+');

axis([0 20 0 20]);

xlabel('time');

ylabel('yp position');

title('the track of movement with noise');

save initial_track
s

谢谢
