我是靠谱客的博主野性烤鸡，最近开发中收集的这篇文章主要介绍MATLAB程序设计-循环结构，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

while循环

%while循环
sum = 0; i = 1;
x = input('Enter first value:');
while x>=0
    sum = sum+x;
    x = input('Enter next value:');
    i = i+1;
end
mean = sum/i;
fprintf('mean=%fn',mean);

for循环

%for循环
%计算一中的第几天
day_of_month = 0;
disp('spcified date');
year = input('Enter year:');
month = input('Enter month:');
day = input('Enter day:');
%判断是否是闰年
%函数mod判断一个数是否可以被另一个数整除
if mod(year,400)==0     
    lead_year = 1;
elseif mod(year,100)
    lead_year = 0;
elseif mod(year,4)
    lead_year = 1;
else
    lead_year = 0;
end
for i = 1:month-1
    switch(i)
        case{1,3,5,7,8,10,12}
            day_of_month = day_of_month + 31;
        case{2}
            if lead_year==0
                day_of_month = day_of_month + 28;
            else
                day_of_month = day_of_month + 29;
            end
        case{4,6,9,11}
            day_of_month = day_of_month + 30;
    end
end
fprintf('day_num=%dn',day_of_month+day);

判断闰年

%
day_of_month = 0;
disp('spcified date');
year = input('Enter year:');
month = input('Enter month:');
day = input('Enter day:');
%判断是否是闰年
%函数mod判断一个数是否可以被另一个数整除
if mod(year,400)==0     
    lead_year = 1;
elseif mod(year,100)
    lead_year = 0;
elseif mod(year,4)
    lead_year = 1;
else
    lead_year = 0;
end
for i = 1:month-1
    switch(i)
        case{3,5,7,8,10,12}
            day_of_month = day_of_month + 31;
        case{2}
            if lead_year==0
                day_of_month = day_of_month + 28;
            else
                day_of_month = day_of_month + 29;
            end
        case{4,6,9,11}
            day_of_month = day_of_month + 30;
        case{13}
            break;
        case{1}
            continue;
    end
end
fprintf('day_num=%dn',day_of_month+day);
