Abstract

Let R be a finite commutative ring with identity. In this paper, formal expressions of the number of m × n matrices over R of rank r and the number of invertible matrices over R are presented. The number of matrices over R with a given rank and a given number of single unit-entry rows, rows in which a single entry is a unit and all other entries are zero, is finally determined.
