Matrix exponentiation for fibonacci
WebYou are given an integer ‘N’, your task is to find and return the N’th Fibonacci number using matrix exponentiation. Since the answer can be very large, return the answer modulo 10^9 +7. Fibonacci number is calculated using the following formula: F(n) = F(n-1) + F(n-2), Where, F(1) = F(2) = 1. For Example: For ‘N’ = 5, the output will ...

Web17 mrt. 2024 · In this example, we’re using a matrix exponentiation technique to compute the n-th Fibonacci number in logarithmic time. To accomplish this, we raise a 2×2 matrix to the power of n-1 and multiply it with the initial state vector [0, 1]. The resulting matrix contains the n-th and (n+1)-th Fibonacci numbers, and we return the n-th number. The ... Web6 apr. 2024 · In mathematical terms, the sequence Fn of Fibonacci numbers is defined by the recurrence relation F n = F n-1 + F n-2 with seed values F 0 = 0 and F 1 = 1.

WebBut anyway, in this implementation it's not clear why it works, and it needs more explanation. Like why not multiply with the column vector, that was present in the initial solution, that helped get to the matrix exponentiation. Anyway, thanks for the matrix notation hint, and for the more pythonic exponentiation. gasper rice resourcesWebThe easiest way to describe the Fibonacci sequence is with a second order difference equation. Assume F 0 = 0 and F 1 = 1 F k + 2 = F k + 1 + F k The first eight Fibonacci numbers are: F k = 0, 1, 1, 2, 3, 5, 8, 13,... We can solve the sequence with linear algebra.
