I have generated bits of sequence, i reshaped it and it should be appended with the CRC? How to program?

close all;
clear all;
clc;
Data_gen = randint(1,11,255);
D=dec2bin(Data_gen);
conv_in=[];

for index =1:11
  conv_in=[conv_in double(D(index,:))-48];
end
data=conv_in;
y=reshape(data,8,[]).';
z=[y zeros(11,2)];
for ii=1:11
    b=z(ii,:);
    c=b;
    G1 = [1,0,1];
    mL = length(c);
    gL = length(G1);
    count = 0;
    while((mL-count) >= gL)
        msg9 = c(1:gL);
        rem = mod((msg9 + G1),2);
        c(1:gL) = rem;
        j=1;
        shft = 0;
        while(j<=gL)
            if(rem(j)~=0)
            break;
            else shft = j
            j = j + 1;
            end
        end
        count = count + shft;
        c(1:shft) = [];
    end
    j = 0;
    value = 0;
    chksuml = length(c);
    disp(c);
    disp(chksuml);
    for j = 1:chksuml; % convert binary to decimal
        if(c(j) == 1)
          value = value + (2^(chksuml-j));
        end
    end
    dec2hex(value);
    dimension = [0 1];
    size = 8;
    B = padarray(c,size*dimension,'pre');
    r=[];
    r=or(c,B);
end
