Contracted Product of Hypermatrices via STP of Matrices

Published 19 May 2023 in math.NA and cs.NA | (2305.11661v1)

Abstract: An equivalent definition of hypermatrices is introduced. The matrix expression of hypermatrices is proposed. Using permutation matrices, the conversion of different matrix expressions is revealed. The various contracted products of hypermatrices are realized by semi-tensor products (STP) of matrices via matrix expressions of hypermatrices.
