用matlab解一个数学模型某商场对顾客所购买商品实行打折销售,标准如下(商品价格用price表示)：price

代码：
clear
clc
price = input('输入价格（元）：n n');
if price < 200
discount = 0;
elseif price < 500
discount = price * 0.03;
elseif price < 1000
discount = price * 0.05;
elseif price < 2500
discount = price * 0.08;
elseif price < 5000
discount = price * 0.1;
elseif price >= 5000
discount = price * 0.14;
else
'Wrong!'
end
price_new = price - discount

price=input ('请输入商品价格：')
if price<200
zhekou=0;
elseif price>=200&price<500
zhekou=0.03
elseif price>=500&price<1000
zhekou=0.05
elseif price>=1000&price<2500
