| Abstract: | The existence of L'-Solution for two-scale difference equation as f(x)=(2x-n) is inverstigated in this paper. First of all,the matrix is constructed by using the equation coefficient. Second, the sufficient condition for such equation existence L'-solution is given by using characteristic value of the matrix. Finally,three special case of such equations is studied too. |
