LDPC encoding using MATLAB encoder

Hello,

I am writing following code, for encoding data to LDPC encoded bit stream. But it is giving error, Kindly help,

I = randi(1,43200); % INFORMATION BITS
H = dvbs2ldpc(2/3);
l = comm.LDPCEncoder(H);
codeword = encode(l,I);

-----> Error using encode

Not enough input arguments.

I = randi([0 1],43200,1); % INFORMATION BITS
H = dvbs2ldpc(2/3);
l = comm.LDPCEncoder(H);

Warning: comm.LDPCEncoder will be removed in a future release. Use ldpcEncode instead. See this release note for more information.

codeword = l(I);
