By using the theories of weak similarity of matrices and weak similarity of matrix pairs,the module algebra structures of cyclic groups of Cm are researched over the full matrix algebra of 2×2 on the complex field φ,and all module algebra structures of dihedral groups D2m are characterized over the full matrix algebra of 2×2 up to isomorphism.
