Fast fibonacci python

WebYou can compute next Fibonacci number (k+2) by multiplying matrix on a vector of two previous elements (k + 1 and k). Hence, k + 3 can be computed by multiplying matrix on vector of (k + 2 and k + 1). This equals squared matrix multiplied on (k + 1 and k). So on. Your code simply squares the matrix, taking into account odd powers.
