error using type too many output arguments in matlab

When a script or function outputs too many arguments, it means that either the function is not defined to return that many values or that the function is called with too many output variables. In either case, the error can be handled in the following ways:

1. Use the nargout function to check the number of output variables expected by the function:

main.m
[output1, output2, output3] = myFunction(input1, input2);
if nargout > 3
    error('Too many output arguments!');
end
118 chars
5 lines

In the above example, if the number of output variables expected is greater than 3, the error will be thrown.

2. Use the try-catch block to handle such errors:

main.m
try
  [output1, output2, output3, output4] = myFunction(input1, input2);
catch ME
  fprintf('The following error occurred: %s\n', ME.message);
end

6 lines

In the above example, if myFunction outputs 4 variables instead of 3, then the error will be caught and displayed.

By using these methods, you can handle the "too many output arguments" error in MATLAB.
