This is cool because there's also an explicit equation (Binet) for this!

This solution uses filter from the Signal Processing Toolbox.

Peng Liu on 18 Nov 2015

Yes, it uses filter, but filter is indeed not a toolbox function, but a built-in function. You can fix the error by changing f=y(n-2) to f = y(n)

Jan Orwat on 18 Nov 2015

... and then change first input of filter to [1,-1] and remove +1 from the end of the line.

Test suite is flawed. I had to add a round(x,0) function to the output to make it pass.

Jan Orwat on 3 Jun 2015

Test is correct. Fibonacci Numbers are integers, so your output should be to.
