![F(1) = matrix(1, 1, [1])](/support/helpjp/helpview.aspx?si=6199/file07311/math72.png)
![F(2) = matrix(2, 2, [1, 1, 1, 0])](/support/helpjp/helpview.aspx?si=6199/file07311/math77.png)
![F(n) = [[F(n-1), F(n-1)], [F(n-1), 0]], where*dim*F(n) = dim*F(n-1)+dim*F(n-2)](/support/helpjp/helpview.aspx?si=6199/file07311/math82.png)
