I was studying about matrix exponentiation here and it requires a prerequisite which says that I need to know how to find the nth power of a square matrix of dimension d in O((d^3)log(n)).
But I couldn't find any well-explained article on this topic. Can anyone please provide me with some links to blogs/articles that explain this technique?
You should first know fast exponentiation for numbers. Then you can just do that for matrix, but the multiplying in matrix of size d, takes d^3 time
