The natural question is: what is a good method to iteratively try different algorithms and test their performance. In fact, you can go more deeply into this rabbit hole, and define a general such sequence with the same 3 term recurrence relation, but based on the first two terms of the sequence. The reason your implementation is inefficient is because to calculate Fibonacci(10), for example, you add Fibonacci(9) and Fibonacii(8).Your code will go off and work out what those values are, but since you have already calculated them previously, you should just use the known values, you don't need to . I noticed that the error occurs when it starts calculating Fibosec(3), giving the error: "Unable to perform assignment because the indices on the left side are not. The Fibonacci sequence can also be started with the numbers 0 and 1 instead of 1 and 1 (see Table 1. So they act very much like the Fibonacci numbers, almost. 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.
