The one-loop renormalization-group equations (RGEs) running behavior of quark and lepton mass matrices with general structures are studied simultaneously. Suppose the non-linear terms of RGEs are dominated by the Yukawa couplings of top quark and {\tau} lepton, the unitary matrices that diagonalize the mass matrices of up-type quark and charged lepton in Hermitian basis are found as invariant with energy scale. Based on this result, we can decouple the RGEs and obtain the RGE corrected mass matrices of fermion. As examples, we consider the renormalization-group evolution of fermion matrices with four or five texture zeros and of lepton mass matrices which realize the tribimaximal mixing.
