控制循环退出的关键字Break、Continue和Return

for i = 1:2
    for j = 2:4
        disp(["i = " + num2str(i) + ", j = " + num2str(j)]);
    end
end

for i = 1: 2
    for j = 1 : 4
        if(j == 2)
            continue;   % 结束当前循环(continue后面的语句不再执行)
        end
        disp(["i = " + num2str(i) + ",j = " + num2str(j)]);
    end
end

for i = 1:2
    for j = 1 : 100
        if(j == 2)
            break ; %退出整层循环(一层)
        end
