Hi all, i'm new to matlab and really need help. I've a binary message and three row vectors, red, green and blue. I want to replace 2 bits of each row vector by the binary message till the message ends. I'm unable to move through the message.

Here is the part of my code.

msg='Hello';
Ascii = reshape(dec2bin(msg, 8)', 1, []) - '0';
for i=1:length(Ascii)
    for x=(i):(i+1)
        redLsbVector(x)=Ascii(x);
    end
    for x=(i):(i+1)
        greenLsbVector(x)=Ascii(x+2);
    end
    for x=(i):(i+1)
        blueLsbVector(x)=Ascii(x+4);
    end
end

Also please help when to come out of the loop. Thanks in advance!
