WebApr 26, 2024 · Note also that the notation that I have used for the derivtion of the things here is transposed compared with the standard notation of linear codes, where the generator matrix is defined as an $(k,n)$ matrix, and not as you did with the $(n,k)$ matrix. I did it this way basing on the input you gave for solving the problem. Webh = hammgen (m) returns an m -by- n parity-check matrix, h, for a Hamming code of codeword length n = 2m–1. The message length of the Hamming code is n – m. The binary primitive polynomial that the function uses to create the Hamming code is the default primitive polynomial in GF ( 2^m ). For more details of this default polynomial, see the ...
