NECESSARY AND SUFFICIENT SOLVABILITY CONDITIONS OF ND UNILATERAL MATRIX EQUATION IN PRACTICAL SENSE

In the light of n-D discrete systems in the practical sense which was introduced by Agathoklis in 1983,we first discuss the solvable condition of n-D unilateral matrix equations.Simple and constructive necessary and sufficient solvability conditions are derived.A new method to determine the stability of a n-D discrete systems in practical sense is presented. All the obtained result is illustrated by a example of 2-D systems.
