Plotkin sum
WebIn a linear code over $\mathbb F_q$, in each coordinate position, either all the codewords have a $0$, or each element of $\mathbb F_q$ appears equally often. WebThe Plotkin sum consists of all vectors u u + v, u ∈C and v ∈D. PunctureCode(C, i) : Code, RngIntElt -> Code Given a length n code C, and an integer i, 1 ≤i ≤n, construct a new code C' by deleting the i-th coordinate from each code word of C.

WebDec 16, 2014 · The same happens for the direct sum and Plotkin sum constructions. For all other constructions, we obtain a partial kernel and the corresponding coset representatives. Although we cannot assure which are the final kernel and coset representatives in these cases, we can speed up the kernel computation by starting from a partial kernel and … WebPlotkin (Russian: Плоткин) is a surname of Russian Jewish origin, which indicates a person from Plotki, a name of several villages in Russia, Belarus, and Ukraine.
