Subsequently we analyze the isomorphism relationship between ergodic matrices and the corresponding permutation group . by defining the permutation symbol operation system of ergodic matrices , we constructed a union form to express all existed permutation algorithms 通過在理論上分析遍歷矩陣和置換群的同構(gòu)關(guān)系,定義了遍歷矩陣對應(yīng)的置換運(yùn)算和符號(hào)體系,再統(tǒng)一的框架下表達(dá)各種圖像置亂變換。
