How to use for loop inside switch case?

How can I use for loop inside switch cases? For example

for j=1,2,...,m
switch j
  case 1,2,...,m-1
    y=x(j);
  case m
   y=x(m)^2;
end

What is exact MATLAB coding?

Your example would be best solved using if or some indexing.

If you really insist on a for-loop, you can use curly brackets. Most times there will be a better solution for this, which will increase speed quite a bit compared to a for-loop.

for a=1:4
    switch a
        case {1,3}
            disp('1 or 3')
        otherwise
            fprintf('%d\n',a)
    end
end

Will print:

1 or 3
2
1 or 3
4
