MATLAB允许在另一个循环中使用一个循环。以下部分显示了一些示例来说明这一概念。
MATLAB中嵌套的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
让我们使用嵌套的for循环显示从1到100的所有质数。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; %如果找到了因子,就不是质数 end end if(j > (i/j)) fprintf('%d is prime\n', i); end end
运行文件时,它显示以下结果-
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
