Hello Cici. We can solve this by introducing another variable count into the function as shown below.
function[F_n, count] = Fibonacci(n, count) count = 1; if n == 2 F_n = 1; elseif n == 1 F_n = 0; else [F_n_1, count_1] = Fibonacci(n-1); [F_n_2, count_2] = Fibonacci(n-2); F_n = F_n_1 + F_n_2; count = count + count_1 + count_2; endendNow your function returns both the 
Fibonacci number as well as the number of times the function was called.
Fibonacci number as well as the number of times the function was called.You may capture only the count in variable ans using this code snippet for the desired value of n.
[~, ans] = Fibonacci(n);Hope this helps. :)
No, the order of the explanatory variables in X is irrelevant. The terms come into the model in the order in which they most improve the fit.
You might want to consider also using the function STEPWISE (not to be confused with STEPWISEFIT), which provides a simple graphical output of what's going on with the terms, step by step.
