How to create a loop?

How can I loop this code such that after getting the answer the code should re run by itself?

clear all
clc
format longG;
format compact;
txt = input ('Choose a Production Period: 1) Annual 2) Monthly 3) Weekly 4) Daily');
    
if txt == 1 
    prompt = "Input Annual Production Target:";
    ProdTarget = input(prompt)
    disp("The production target (MT) per shift should be")
    ProdTarget_PerShift = ProdTarget/10/4/7/2

elseif txt == 2 
    prompt = "Input Monthly Production Target:";
    ProdTarget = input(prompt)
    disp("The production target (MT) per shift should be")
    ProdTarget_PerShift = ProdTarget/4/7/2

elseif txt == 3 
    prompt = "Input Weekly Production Target:";
    ProdTarget = input(prompt)
    disp("The production target (MT) per shift should be")
    ProdTarget_PerShift = ProdTarget/7/2

elseif txt == 4 
    prompt = "Input Daily Production Target:";
    ProdTarget = input(prompt)
    disp("The production target (MT) per shift should be")
    ProdTarget_PerShift = ProdTarget/2
    
else
    disp("INVALID") 
end

Introduce a while loop inside the if-else conditions for the given input selections by the user. That will allow the code to run iteratively till the desired value is obtained using while loop conditon.

There are several ways in which you can re-run the code, e.g shown above is another method
