[MATLAB基础] 大家能帮我看一下这段程序有什么问题吗

[多多月]

count=[4,1,3,6,1,2,5,7,1,2];
>> NIND=10;
for i=1:NIND
if count(i)==0 R2(i)=0;
else if 0<count(i)<=2 R2(i)=10000000;
else if 2<count(i)<=6 R2(i)=20000000;
else if 6<count(i)<=10 R2(i)=30000000;
else R2(i)=60000000;
end
end
end
end
end
运行结果总是是R2 =

Columns 1 through 8

10000000 10000000 10000000 10000000 10000000 10000000 10000000 10000000

Columns 9 through 10

10000000 10000000
我改变count的值，可结果还是一样的，哪位高手能告诉我问题出在哪里呀，先谢谢啦！
