An equivalence relation in the set of two-dimensional matrices

We define an equivalence relation in the set of two-dimensional matrices. The algorithms for investigation of the equivalence of two matrices are presented. We also present the procedure for determining the automorphism group of a matrix regarding that equivalence relation, which is based on using the set of strong generators. Furthermore, we define the preceding relation and describe the algorithm for determining the first matrix in a particular equivalence class regarding that preceding relation.
