How can I solve this error with MATLAB CODER?

Hi,

I am New to MATLAB. I am trying to convert the following MATLAB code to C code using MATLAB coder but I am getting the following error in the scrren shot.

Can someone please help me with this?

Regards,

Y

function [Conv_out] = conv_enc_test(Conv_In)

Conv_In = [1,0,1,0,1]; 
Conv_out = [];

m1=0;
m2=0;
m3=0;
m4=0;


for k = 1:length(Conv_In)
%%1st polynomial


m_in = Conv_In(k);

%first polynomial
temp1 = bitxor(m_in,m2);
x0 = bitxor(temp1,m4);

%2nd polynomial
temp1 = bitxor(m_in,m1);
temp2 = bitxor(temp1,m3);
x1 = bitxor(temp2,m4);



Conv_out((2*k)-1) = x0;
Conv_out(2*k) = x1;

%%%Shifiting
m4=m3;
m3=m2;
m2=m1;
m1=m_in;

end

In your example you can certainly preallocate the variable:

Conv_out = zeros(1,2*length (Conv_In));
