hi, I have made the following program which is used for refinement in image coding. mark=zeros(1,4); out1=zeros(1,4); out=zeros(1,4); x=[1 3 7 8]; for n=3:-1:1; t=2^n; for i=1:4; if (x(i)>=t);
switch mark(i)
case 0
out1(i)=sign(x(i));
mark(i)=1;
case 1
z=dec2bin(x(i),4);
out1(i)=z(1);
mark(i)=2;
case 2
z1=dec2bin(x(i),4);
out1(i)=z1(2);
mark(i)=3;
otherwise
end
else
out1(i)=0;
end
end
end
when I run this program I get finally out1 as 0 1 48 48 . Instead I should get 0 1 0 0. Can any body tell me what is the problem with my program.
