Construction of Ternary Bent Functions Trough Matrix Representations

Functions in a large number of variables necessarily require large function vectors to be represented. For a p-valued function, such a vector of length \(p^{n}\) can be split into subvectors of equal size \(p^{n-k}\) for various values of k which can be arranged as either rows or columns of a matrix. Sometimes, such matrices can be viewed as a more suitable data structure for manipulating and computing with given functions.
