clc;
close all;
in_st = [0.5 , 0.5] ;
s = [0.9,0.1;0.9,0.1];
r = [0.25 , 0.75];
b = [0.75 , 0.25];
inp = [1,2,2];
alpha = zeros(2,length(inp));
p1 = in_st(1);
p2 = in_st(2);
if(inp(1) == 1)
alpha(1,1) = p1 * r(1);
alpha(2,1) = p2 * r(2);
end
if(inp(1) == 2)
alpha(1,1) = p1 * b(1);
alpha(2,1) = p2 * b(2);
end
for i = 2 :length(inp)
if(inp(i) == 1)
alpha(1,i) = (alpha(1,i-1) * s(1,1) + alpha(2,i-1)*s(2,1)) * r(1);
alpha(2,i) = (alpha(1,i-1) * s(1,2) + alpha(2,i-1)*s(2,2)) * r(2);
end
if(inp(i) == 2)
alpha(1,i) = (alpha(1,i-1) * s(1,1) + alpha(2,i-1)*s(2,1)) * b(1);
alpha(2,i) = (alpha(1,i-1) * s(1,2) + alpha(2,i-1)*s(2,2)) * b(2);
end
