在matlab中，如何在中间停止ifelse条件并再次从top开始？

Question

例如，我有

some calculations from some formulae
calculate r

if r<1
something
(the point where I want to discontinue and start the above calculations again)

else if r>tau
something

else if r==0
something

else
something

some calculations again after this

如果满足第一个条件（r＆lt; 1），我怎样才能中断if / else并从顶部重新开始所有计算（r <1）...... ??

Answer 1

你可以实现这个循环：

finished=false;
while ~finished
    %default case, finish if case is done
    finished=true;
    if r<1
        something
        %start from begin in this case:
        finished=false;
    elseif r>tau
        something
    elseif r==0
        something
    else
        something
    end

end

Answer 2

如果您的计算在一段时间内或for循环中完成，请使用CONTINUE或BREAK命令。
