MATLAB嵌套循环

MATLAB嵌套循环允许使用一个循环的另一循环内。

MATLAB嵌套循环语法:

在 MATLAB 中嵌套 for 循环语句的语法如下：

for m = 1:j
    for n = 1:k
        <statements>;
    end
end

在 MATLAB 中嵌套 while 循环语句的语法如下：

while <expression1>
   while <expression2>
       <statements>
   end
end

详细例子

我们将使用一个嵌套循环来把所有从1到100的素数显示出来。

现在MATLAB中建立一个脚本文件，并输入下述代码：

for i=2:100
       for j=2:100
        if(~mod(i,j)) 
            break; % if factor found, not prime
        end 
      end
      if(j > (i/j))
          fprintf('%d is prime
', i);
      end
end

然后运行该文件，显示如下结果：

2 is prime
3 is prime
5 is prime
7 is prime
11 is prime
13 is prime
17 is prime
19 is prime
23 is prime
29 is prime
31 is prime
37 is prime
41 is prime
43 is prime
47 is prime
53 is prime
59 is prime
61 is prime
67 is prime
71 is prime
73 is prime
79 is prime
83 is prime
89 is prime
97 is prime
