Matlab替代try/catch或catch后继续

Question

我试图为一个可能存在也可能不存在的图像文件设置70多个tiff标记。如果我试图设置一个标记，但由于该标记在img文件中不存在而引发异常，我想继续尝试设置剩余的标记，并且我不想按顺序有70个try/catch语句。

有没有办法让它立即继续执行它停止的地方？

例如：不是

try
%matlab code to set tag1
catch ME
%do nothing
end
try
%matlab code to set tag2
catch ME
%do nothing
end
try
%matlab code to set tag3
catch ME
%do nothing
end

而是这个：

try
%Matlab code to set tag1, continue regardless of exception
%Matlab code to set tag2 continue regardless of exception
%Matlab code to set tag3, continue regardless of exception
catch ME
%do nothing skip this tag and execute next line up there ^^^
end

您可以在while循环中使用trycatch：

count = 0;
err_count = 0;
while count == err_count
try
% my attmept to understand the tags you asked about
if  your_tag_number(count) ~= the_tag_you_want;
error
end
catch ME
err_count = err_count + 1;
end
count = count + 1;
end
