On the lower bound of cost of mds matrices
http://www.mmrc.iss.ac.cn/~dwang/papers/20jssc1.pdf WebMDS matrices are derived from MDS codes. An [n, k, d] code C is MDS if it meets the singleton bound d = n − k + 1. MDS matrices have the maximum differential and linear branch number (k + 1 for k × k MDS matrices) [15]. Some important properties of MDS matrices can be given as follows: i. A k × k matrix M is MDS if and only if every square …
