看到书上归一化代码写得不对吧?比如
p=[1520,510,5.155,33.88;1468,521,5.321,35.79;2412,1140,5.32,25.89;1750,129,4.7,23.8;...
1688,261,4.865,27.08;1607,489,5.1,28.9;1200,127,4.56,19.84;1990,148,4.89,29.373;1509,511,5.12,34.3;...
1730,133,4.46,23.06];
for i=1:4
P(i,:)=(p(i,:)-min(p(i,:)))/(max(p(i,:))-min(p(i,:)));
end
输出P值为:
P =
    1.0000    0.3333         0    0.0190
    1.0000    0.3526         0    0.0208
    1.0000    0.4715         0    0.0085
    1.0000    0.0712         0    0.0109
显然不对吧?可书上都这么写的,怎么回事呀?
