Talk:Fibonacci matrix-exponentiation
Clarify Task
The task to implement fib(n) using matrix multiplication is a great task. However, given that fib(2^32) has hundreds of million of digits, the task is unachievable. Many implementations use fibMod for the last digits, and another methodology for the first digits. Recommend a selecting smaller values of n, and sticking to the task of fib(n) using matrix multiplication, not fibMod or other implementations.
