MATLAB嵌套循環

MATLAB允許使用一個循環的另一循環內。下麵的部分顯示了幾個例子來說明這個概念。

語法:

嵌套在 MATLAB 中的循環語句的語法如下:

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

在MATLAB中嵌套 while循環語句的語法如下:

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

例子

讓我們用一個嵌套循環來顯示所有的素數從1到100。創建一個腳本文件,並鍵入下麵的代碼:

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

當您運行該文件,它會顯示以下結果:

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
