switch matlab_review
case 'good' || case 'interesting'
fprintf('Review is positive\n');
otherwise
fprintf('Not so good review\n');
end

@Akhil Reddy: did you read the switch documentation? It explains exactly how to do this... and it has examples too!

在 MATLAB Online 中打开

As per the documentation of switch, case, otherwise, to include several possible match for a case, group them in a cell array.

switch matlab_review
case {'good', 'interesting'}
   fprintf('Review is positive\n');
otherwise
   fprintf('Not so good review\n');
end

It's always a good idea to read the documentation rather than trying to make up your own syntax.

Just an observation here. The documentation talks about combining test cases as you have correctly pointed out. But it doesn't talk about combining a case and a "default" case. For instance, in your example, it is not cleat if it is acceptable to combine {'good', 'otherwise'}.

It matters because "otherwise" is a special case.
