MATLAB - 嵌套循环
MATLAB 允许在一个循环内使用另一个循环。 以下部分显示了一些示例来说明该概念。
语法
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
MATLAB 中嵌套 while 循环语句的语法如下 −
while <expression1> while <expression2> <statements> end end
示例
让我们使用嵌套的 for 循环来显示从 1 到 100 的所有素数。创建一个脚本文件并键入以下代码 −
for i = 2:100 for j = 2:100 if(~mod(i,j)) break; % 如果找到因子,则不是素数 end end if(j > (i/j)) fprintf('%d is prime\n', i); end end
当您运行该文件时,它会显示以下结果 −
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
