Sorry. I think it’s only the jargon that’s confusing you. As long as you can remember (or look up) the definition of matrix multiplication, then it genuinely is easy to verify. [ fib(n-1) fib(n) ] x [0 1] [ fib(n) fib(n+1) ] [1 1] = [ fib(n) fib(n-1)+fib(n) ] [ fib(n+1) fib(n)+fib(n+1) ] = [ fib(n) fib(n+1) ] [ fib(n+1) fib(n+2) ]
