Question 11. How do you handle errors in MATLAB?
Errors in MATLAB can be handled using 'try', 'catch', 'finally' blocks. The 'try' block contains the code to be executed, the 'catch' block handles errors, and 'finally' contains cleanup code.
Example:
try
% MATLAB code that may cause an error
error('Custom error message');
catch exception
disp(['Error: ', exception.message]);
finally
% Cleanup code
end
