        for i = 1:65535
            RR(i+1)=mod((double(R(i))+GG(i)+BB(i)),256);
            GG(i+1)=mod((RR(i)+double(G(i))+BB(i)),256);
            BB(i+1)=mod((RR(i)+GG(i)+double(B(i))),256);
        end
        for i = 1:65536 
            RRbin(i) = [ fix(rem(fix(RR(i))*pow2(-(16-1):0),2)), fix(rem( rem((RR(i)),1)*pow2(1:20),2))];
end

This is the code which i used to convert the decimal values in RR to binary. But the error message is as In an assignment A(I) = B, the number of elements in B and I must be the same. There are 65536 values in RR. How could i solve this ?

What about variables other than RR? What are their sizes? At which line the error comes up?

RR, GG, BB are all of size 1x65536 double. I need to convert all these to binary. When i tried the given code in RR the error comes at that line RRbin(i)
