Enumerator polynomial
（重定向自Weight enumerator）
In coding theory, the weight enumerator polynomial of a binary linear code specifies the number of words of each possible Hamming weight.
Let ![C \subset \mathbb{F}_2^n](/Images/godic/202502/20/1d400d1a515d59e5dd0fa694a501a9794257.png")
be a binary linear code length ![n](/Images/godic/202502/20/7b8b965ad4bca0e41ab51de7b31363a14257.png")
. The weight distribution is the sequence of numbers
giving the number of codewords c in C having weight t as t ranges from 0 to n. The weight enumerator is the bivariate polynomial
