>> [attrib1, attrib2, attrib3, attrib4, class] = textread('data\iris.data', '%f%f%f%f%s', 'delimiter', ','); >> attrib = [attrib1'; attrib2'; attrib3'; attrib4']'; >> a = zeros(150, 1); >> a(strcmp(class, 'Iris-setosa')) = 1; >> a(strcmp(class, 'Iris-versicolor')) = 2; >> a(strcmp(class, 'Iris-virginica')) = 3;
至此，属性值均保存到attrib中，类别值保存到数组a中。
