MATLAB: Repeating a sequence of code

MATLABrepeating codesrepeating loops

Hello,
I am working on an assignment for a class, I have a program written as follows,
disp(' Choose an Option Below ');
disp(' 1 Convert Decimal Number to Binary Number');
disp(' 2 Convert Binary Number to Decimal Number');
disp(' 3 Exit');
n = input(' Enter Option Number You Desire: ');
switch n
case 1
fprintf(' Convert Decimal Number to Binary Number\n');
a = input(' Please enter a whole decimal number: ');
bradleyJohnsonD2B(a)
case 2
fprintf(' Convert Binary Number to Decimal Number\n');
b = input(' Please enter a binary string : ');
johnsonBradleyB2D(b)
case 3
fprintf( ' Thank you for using my program !!\n ');
otherwise
fprintf( ' You Selected an Invalid Option, Please Choose Again ');
end
I need this program to start over or repeat its self from the beginning for every option other than case three. how would I go about doing that.

Do you mean this?
n = 1;
while n ~= 3
    disp(' Choose an Option Below ');
    disp(' 1 Convert Decimal Number to Binary Number');
    disp(' 2 Convert Binary Number to Decimal Number');
    disp(' 3 Exit');
    n = input(' Enter Option Number You Desire: ');
    switch n 
        case 1 
            fprintf(' Convert Decimal Number to Binary Number\n');
            a = input(' Please enter a whole decimal number: ');
            bradleyJohnsonD2B(a)
        case 2
            fprintf(' Convert Binary Number to Decimal Number\n');
            b = input(' Please enter a binary string : ');
            johnsonBradleyB2D(b)
        case 3 
            fprintf( ' Thank you for using my program !!\n ');
        otherwise 
            fprintf( ' You Selected an Invalid Option, Please Choose Again ');
    end
end
