How to do the DoubleDown function?

 function finalValue = DoubleDown( initialValue )

    % Complete the function to return twice the initialValue
    finalValue = 0; 
    %supposed to make finalValue = 10 and then 240

end

@Blair: "return twice the initialValue" seems to be very clear already. "twice" means "2 *". What exactly is your problem?

[Blair Hall]

What do I put in to make return both numbers. I don't know if the picture is visible but there is a box under the main one shown and it says something like 'Code to Call your Function.' In the box it already has DoubleDown(5) % Change the input to DoubleDown to test other values.

[Geoff Hayes]

DoubleDown(5) is how you call your function from the command line (or from within another function). Calling your code like this

 >> DoubleDown(5)

should return

 ans = 
     10

Presumably the second number (240) is returned when you call your function as

 >> DoubleDown(120)

function finalValue = DoubleDown( initialValue )
    
    % Complete the function to return twice the initialValue
    finalValue = 2*initialValue; 

end

%This code worked foe me! Hope it works for you as well!
