I want to find eigenvalu and eigenvector using "eig" function in matlab, but sometimes I get this error:
Error using eig EIG did not converge.
how can I avoid this error or what can I do the code run again automatically if this error happens?

Are you looking for TRY/CATCH?

You explained, that your code fails sometimes. Then including the failing command in TRY/CATCH allows to run a fallback method or some error handling:
try
[V, D] = eig(X);
catch ME
warning(ME.message);
[V,D] = EIG(X, 'nobalance'); % For example
end
It depends on your calculations, if the problem can be avoided or what "automatic" can help get the wanted result. Without knowing any details about your code, I can suggest only a general strategy.
