关于#matlab#的问题：用Matlab求

用Matlab求[100，300]之间第五个能被21整除的整数。注：使用continue或break语句

n=100;
targetSeq = 5;
targetValue = 0;
NowSeq = 0;
while n<=300
    if(mod(n,21)==0)
        NowSeq = NowSeq+1;
        if(NowSeq==targetSeq)
            targetValue=n;
            break;
        else
            n=n+1;
            continue;
        end
    end
    n=n+1;
end
