So they act very much like the Fibonacci numbers, almost. But now how fibonacci(2) + fibonacci(1) statement would change to: I am receiving the below error and unable to debug further to resolve it: Please provide some insight for the solution and with which parameter would fibonacci function be recursively called at line number 9 first and consequently. Also, if the input argument is not a non-negative integer, it prints an error message on the screen and asks the user to re-enter a non-negative integer number. Why are physically impossible and logically impossible concepts considered separate in terms of probability? Unexpected MATLAB expression. MATLAB Profiler shows which algorithm took the longest, and dive into each file to see coding suggestions and which line is the most computationally expensive. Which as you should see, is the same as for the Fibonacci sequence.
