How to automatically continue running the program after an error.
显示 更早的评论
The problem I'm having is currently with the GMM fit model. but it's rather general. during the run of my program GMM sometimes gives the error of ill conditioned matrix and breaks the code. Now my code is in a long loop with a counter. what I'm doing right now is to manually reset the loop counter in the code body to the last working number, so that the code restarts from the point where it stoped. But it's tedious. Is there a way to tell matlab to do a few basic operations in case of an error and try again, instead of breaking off with an error?

counter = 1;
while counter <= num_loop %if you want to retry the loop, you need to change it into a while loop
%... some code
try
%some operation that may terminate
catch err
if strcmp(err.identifier, 'whatever identifier is thrown by GMM')
counter = counter - 1; %retry loop
else
rethrow(err); %some other unexpected error. Better stop
end
end
counter = counter + 1;
end

You should try to catch the error using the structure try/catch structure:
try
statements
catch exception
statements
end
