for loop for switch case

I have a switch case:

switch test
    case test1
        x=user_defined_value
        a=x+1 
    case test2
        x=user_defined_value
        a=x+2
end

I want the user to be able to iterate through one case several times. For example, x=[1,2,3,4] for case 'test2' like a forloop. How would I do this?

would arrayfun work for your code? It would handle both x as a single number and x as a vector, setting 'a' to a single number or a vector to match the input

x = 1;
arrayfun(@(P) P+2, x)
ans =
     3
x = [1 2 3 4];
arrayfun(@(P) P+2, x)
ans =
     3     4     5     6
