As we mentioned earlier, this convergence is really slow if the matrix is poorly conditioned.

WebbThe nth power of a matrix is an expression that allows us to calculate any power of a matrix easily. Many times powers of matrices follow a pattern. Therefore, if we find the sequence that the powers of a matrix follow, we can calculate any power without having to do all the multiplications.
