      Abstract:

      According to the idea of matrix core-nilpotent decomposition, by applying the related properties of Drazin inverse, simple formulas of the sum of two matrices under certain conditions are given.

      Key words:

      sum of matrices; Drazin inverse; core-nilpotent decomposition
