一个有关海明码的原程序！！适合教师实验课讲授！-A Hamming code of the original program! ! Experimental courses for teachers to teach!

decoder of Hamming Use a [7,4] Hamming code. m = 3 n = 2^m-1 k = n-m parmat = hammgen(m) Produce parity-check matrix. trt = syndtable(parmat) Produce decoding table. recd = [1 0 0 1 1 1 1] Suppose this is the
