Abstract
In this paper, the matrix representations and interdependency of a pair of L-fuzzy covering-based approximation operators are investigated. The aim of matrix representations of lower and upper approximation operators is to make calculation more valid by means of operations on matrices. Furthermore, in accordance with the concept of \(\beta \)-base, we give a necessary and sufficient condition under what two L-fuzzy \(\beta \)-coverings can generate the same lower and upper approximation operations.
