How to restart my program from a try/catch statment

I am trying set up a try/catch statment for error detection within my program.

If an error occurs in the try statment, i would like to change a variable (by -1) and then retry the entire program, How to i go about this?

With recursion, you could do something like this:

val = 1;
startThisAgain(val)

Beginning Program
Trying
Caught
Beginning Program
Trying
Done!

function startThisAgain(val)

    disp('Beginning Program')
    
    try
        disp('Trying')
        assert(~mod(val,2) == 1,'This is an error')
        disp('Done!')
        
    catch
        disp('Caught')
        val = val+1;
        startThisAgain(val)
        
    end
end
