Can I execute only one case inside multiple cases inside switch ?

The code below is execution the cases randomly, for example in the first round 3 1 2 in the second round 2 1 3 and so forth. my question can I execute only one case each round, for example in the first round case 2 is executed and in the second round selecting case 1 and so forth. ?

thanks in advance

for jj=1:20
    for randCases=randperm
        switch randCases
            case 1
                for best_1
                    for i_1
                        do calculation
                    end
                end
            case 2
                for best_2
                    for i_2
                        do calculation
                    end
                end
            case 3
                for best_3
                    for i_3
                        do calculation
                    end
                end
        end
    end
end

Yes, you can execute it single case from each round by adding an extra for loop

% define round sequence 
randCases=randperm(3,3)

randCases = 1×3

1 3 2

% add an extra loop 
for k = 1:length(randCases)
        switch randCases(k)
            case 1
                for best_1
                    for i_1
                        do calculation
                    end
                end
            case 2
                for best_2
                    for i_2
                        do calculation
                    end
                end
            case 3
                for best_3
                    for i_3
                        do calculation
                    end
                end
        end
end

First thank you for your response, But this way exactly works same as the way in my question code...My question was if I could select only one case, the round that I mean is round of the outer loop

for jj
    
end

this is the outer loop my question was If I could execute a single case randomly each round, for example when jj =1 select case 2 and when jj=2 select case 3 and spo forth...
