array1 = [1 2 3]; % this will change in the program
array2 = [4 5 6]; % this will change in the program
switch anyVariable
case {array1}
disp('1')
case {array2}
disp('2')
otherwise
disp('3')
end
This always displays 3, irrespective of the value of anyVariable. Shall I change it to if-elseif kind structure?

Use cell arrays, where each cell contains one scalar numeric (or a char vector):
V1 = {1,2,3};
V2 = {4,5,6};
switch scalarVal
case V1
disp('one')
case V2
disp('two')
otherwise
disp('none')
end

Only after viewing the comment I tried to execute that (Thanks for the comment). It can be a nice feature to add.

@Pramit Biswas: you can convert numeric row vectors to char (as long as they are suitable, i.e. positive integers, etc).
