模糊數(shù)學(xué)聚類分析-matlab作聚類分析圖

實(shí)驗(yàn)一：聚類分析要求：把照片分類一例（即例3），編程序做一遍。

照片分類?，F(xiàn)有三個(gè)家庭，每個(gè)家庭由四至七人組成，每人一張照片，共有十六張。通過照片按相貌相像程度分類，把三個(gè)家庭區(qū)分開來。首先，建立相似關(guān)系。任取兩張照片，請若干中學(xué)生按相貌相像程度打分，取平均數(shù)再折合成隸屬度，得到相像關(guān)系的F矩陣R（見表）由于矩陣是對(duì)稱的，只寫出下三角。101001000.4100.80010.500.20.20100.8000.4010.40.20.20.500.80100.400.80.40.20.401000.20.2000.200.2100.50.20.2000.800.40.21000.20.800000.40.8010.800.20.400.400.40000100.800.20.400.800.20.20.6001000.40.800.2000.2000.20.2010.6000.20.20.800.400000.40.20.41表1模糊矩陣A=[100000.500.400000.8000.6;
