class1='ST';
class2='AK';
class3='SN';
for j=1:size(mean1,1)
if (0<mean1(j))&(mean1(j)>=60)
class=class1
end
if(61<=mean1(j))&(mean1(j)>=80)
class=class2
end
if(81<=mean1(j))&(mean1(j)>=100)
class=class3
end
end

elseif(61<=mean1(j))&(mean1(j)<80), class=class2;
else class=class3;
end
out = [out;{class}]
