create function that displays fibonacci series

So, I have four goals here: the user will input the first two numbers of fibonacci series, and the length of the series (n). Fourth goal: function will output 'n' numbers of the Fibonacci series (starting at the two numbers that the user entered).

I've been at this for two hours (youtube videos and all), yet all I've been able to come up with is this:

   function FibLength = myFibonacci(n)

    if n==0||n==1
        FibLength= n;
    else

        FibLength= myFibonacci(n-2)+myFibonacci(n-1)

    end

Which , by the way, just prints out the 'nth' number of the Fibonacci series. Can someone guide me here please?

Your line

          FibLength= n;

does not adhere to the condition that the user was able to input the first two values of the series.

The first two values of the series are considered to correspond to n = 1 and n = 2 by the way.
